Ricky Ricotta's Mighty Robot vs. the Unpleasant Penguins from Pluto book cover

Ricky Ricotta's Mighty Robot is a series of children's graphic novels written by Dav Pilkey (best known for his Captain Underpants books) and first seven books illustrated by Martin Ontiveros and all nine books, including two long-awaited sequels, illustrated by Dan Santat. In each book, Ricky Ricotta, a mouse, with the help of his mighty robot, saves the world from an evil villain. Also, the books each have an alien creature from a different planet in order from closest-to-sun to farthest-from-sun including Earth, as the villain of the first book is from Earth. The reader could see the villains being jailed in each series and later notice the familiar villains from previous books.

Publication history

The first three books were originally published as Ricky Ricotta's Giant Robot. Dav Pilkey stopped using the word Giant in the year 2002 after many young fans pointed out that the Robot really isn't a giant. He's just 12 times taller than a mouse, so he's really only about two and a half feet tall. Many young readers suggested the adjective "Mighty" instead, so after careful consideration, Pilkey changed the title on all the books.

Dan Santat replaced Martin Ontiveros as illustrator in 2014 and had the first seven books re-drawn by Santat plus illustrated the remaining two books that were not published with Ontiveros as illustrator. The books 1 through 5 with Santat's illustrations released in 2014, books 6 and 7 released in 2015 while the new books 8 and 9 released in 2016. This happened that back in 2012, a Ricky Ricotta fan in Canada begged Pilkey for more Ricky Ricotta books and shortly after that, his editor and the publisher decided to not only create more Ricky Ricotta books, but also to re-illustrate the previous books modernly in colors plus add never-before-seen mini-comics. Pilkey's editor asked who he wanted for re-illustrations and he chose Dan Santat as the only illustrator in mind and fortunately for Pilkey, Santat agreed to re-illustrate all seven books, plus illustrate two new remaining, unpublished Ricky Ricotta's Mighty Robot adventures.

The book was originally called Ricky Ricotta's Giant Robot. However, it was changed because he is only about 12 times taller than a mouse, and therefore, that does not make him very tall.

Ricky Ricotta is a lonely mouse who lives in Squeakyville. He always wishes he had a close companion to keep him company. Once he starts school, he gets bullied because of his small size. He was full of sadness because the bullies picked on him. Ricky wishes that something big would happen. In a secret cave on the mountain top, the crazed rat scientist, Dr. Stinky McNasty, creates a giant robot to destroy Earth. When the robot refuses to do so, Dr. McNasty zaps the robot as punishment. Luckily, though, Ricky happens to be watching at the time. He kicks a ball at the deranged doctor, and the ray gun is smashed, forcing McNasty to retreat. When the robot sees what Ricky has done, Ricky befriends the robot. Ricky shows to his parents, teachers, and schoolmates how helpful the robot can be, but since the robot can't fit in the house, Ricky resorts to stashing him in the garage.

Meanwhile, Dr. McNasty is plotting revenge. He brings along a potion of hatred and feeds it to the classroom lizard. The lizard becomes Dr. McNasty's new, more obedient servant, and starts attacking. After Ricky's robot pal bests the lizard in battle, the lizard returns to normal. Enraged at what has just happened, Dr. McNasty decides to destroy the robot himself. He pulls out a rocket launcher, but Ricky jumps at him just as he pulls the trigger. The rocket ends up landing on Dr. McNasty's secret cave, destroying it. Dr. McNasty grows angry when it was a bad day for him. Together, Ricky and his robot imprison the scientist. In the cookout, Ricky talks to his parents about the adventures. He therefore hopes his Mighty Robot will be by his side when he says the line, That's what friends are for.

The story opens with a demonstration of how Ricky's robot helps him out. Ricky looks through the robot's telescopic eye, sees all the way to Mercury, and thinks it's cool. But Mr. Mosquito doesn't think the same thing, since he lives on Mercury. He hates the extremely hot days, and the very cold nights, so he tries to find a place with more favorable conditions. He decides on Earth, and creates 'Mutant Mosquitoes' which he uses to take the world over. Meanwhile, Ricky spots the Mutant Mosquitoes and he asks his teacher if he can go, but he is refused because he has to finish his math test first. Thanks to Ricky's Robot, he solves the final problems in a jiffy. The Mighty Robot defeats the mosquitoes with a spray, sending them back to Mercury. Angry, Mr. Mosquito drags Ricky into his ship, turning his ship into a Robotic Mecha-Mosquito, which battles Ricky's robot. However, Ricky's Robot refuses to fight back, because it is worried if it does, Ricky will get harmed. Ricky distracts the mosquito by requesting to use the restroom and climbing out of the window. His robot fights and wins the battle. He cries when he thinks he had a bad day. Mr. Mosquito is then locked up afterwards. In the end, they go home with milk and grilled cheese. Ricky therefore hopes his robot will be by his side.

Ricky Ricotta's Mighty Robot vs. the Voodoo Vultures from Venus (2001) is by Dav Pilkey and illustrated by Martin Ontiveros (2001 version) and Dan Santat (2014 version), the third in the series. The title was later updated to change "Voodoo" to "Video." Throughout the revised version, Ricky and his Mighty Robot combat Video Vultures instead of Voodoo Vultures.

The story starts when Ricky Ricotta and his Mighty Robot are late for supper because they were in the capital of Hawaii, collecting seashells. Ricky's mom says that he has been late for supper all week, and tells Ricky and his Mighty Robot that they cannot watch TV until the both of them learn their own responsibility. Since the Mighty Robot is unfamiliar with the meaning of responsibility, Ricky decides to explain that it means doing the right things at the right time. Of course, while the duo are good at the right things, they have trouble with doing them at the right time. Ricky and his robot sleep under the stars, while every other mouse in Squeakyville is watching TV.

Meanwhile, on Venus, the Voodoo Vultures want to eat good food, so they shoot a laser beam to all of the TVs in Squeakyville. All of the TVs then start hypnotizing the mice who were watching TV. Ricky and his Mighty Robot realizes the next morning that the mice are hypnotized and were ordered to take food to the army of Voodoo Vultures. Ricky comes up with a plan to make chocolate chip cookies, which are stuffed with hot chili peppers. Ricky then pretends to be hypnotized and takes the cookies to the vultures. The Voodoo Vultures fall for the trick, and dance around in pain from the spicy taste. This gives the Mighty Robot some time to break the remote control. The Squeakyville mice are now free from hypnosis, and they all flee back to their houses. Ricky's Mighty Robot then battles against the Voodoo Vultures. In the end, the Mighty Robot wins the fight. The Voodoo Vultures then fly back to Venus, except for the Voodoo Vultures' tyrant, Victor Von Vulture. The Mighty Robot and Ricky then put him behind bars and Ricky arrogantly brags at him saying that he needs to learn responsibility. Ricky and his Mighty Robot then come home on time as Ricky's parents are very proud of them for learning their own responsibility and the story ends with Ricky and his Mighty Robot watching Rocket Rodent on TV.

On the planet Mars, Major Monkey still feels lonely, even after building a number of machines for company. So he decides to enslave the mice on Earth ... but not before disposing of the Mighty Robot first.

With the robot captured, Major Monkey and his army of Mecha-Monkeys launch an all-out assault on Squeakyville. Ricky feels bad about what's happened to his friend, and wonders what to do about it.

The Mighty Robot takes the shuttle back to Earth, and after fighting the rest of the machines, Major Monkey is imprisoned for his evil deeds. He is peeved because the monkeys are monkeying around. When the monkeys go back to Mars, Major Monkey boohoos as if he made a big mistake but Ricky tells him to pay for his mistake.

Ricky Ricotta and his Robot visit Ricky's Uncle Freddie and Aunt Ethel, and his annoying cousin Lucy. Ricky gets irritated because Lucy always wants to play Princess. (thinking Lucy will be the princess, Ricky will be the ugly prince, Cupcake, Fudgie, and Waffles will be the royal ponies and the Mighty Robot will be the brave knight) Meanwhile, on the dark, smelly, polluted world of Saturn, Sergeant Stinkbug grows tired of the planet and decides to find another world to dump junk.

When he sees Lucy, Sergeant Stinkbug swoops down to Earth and kidnaps her while Ricky and his robot and the three Jurassic Jackrabbits (Cupcake, Fudgie, and Waffles) are snacking away.

While Sergeant Stinkbug tries to interrogate Lucy, her Jurassic Jackrabbits come to the rescue. But Sergeant Stinkbug summons a few of his greatest warriors and gives them "Grow-Big Gumballs", causing them to grow. The Mighty Robot battles well against them at first, but Sergeant Stinkbug gives them more Gumballs, making them bigger than they were before. Fudgie and Cupcake manage to swipe the Gumballs from under the stinkbugs' noses, and Ricky chomps them down. Once he is as big as the stinkbugs, he battles against them and wins. But then he soon realizes that he still needs to get rid of the foes. Then he sees that Lucy had the rest of the Gumballs (she enjoys Gumballs so much), and has grown way bigger than anyone else. She grabs the rest of the stinkbugs, stuffs them back inside the spaceship, and hurls them back to Saturn. Fudgie and Cupcake find "Super-Shrinking Saltwater Taffy" and feed it to the two cousins. Once they are back to normal, they throw Sergeant Stinkbug in jail.

When Ricky and Lucy get back and tell everyone what happened, they think it's all just part of a game they were playing. Ricky's father is happy that Ricky played nice with Lucy, though. The book finishes with the heroes celebrating their victory.

Ricky Ricotta's Mighty Robot vs. the Naughty Nightcrawlers from Neptune

Ricky Ricotta's Mighty Robot vs. the Naughty Nightcrawlers from Neptune (2016) is a children's novel by Dav Pilkey and illustrated by Dan Santat. The 8th book in the series, it released in 2016 after spending over a decade in development hell.

Ricky and his Mighty Robot were bored until when his parents got in their car to go shopping, Ricky's mother told him and the Robot not to make any mess while they're gone and then his father gave Ricky an idea of building a fort. While the parents were gone, the mayor of Squeakyville wanted to demolish an abandoned building but it costs money to do so, so Ricky and his Robot saved the mayor's trouble by tearing down the building for free. With all the debris from the building, Ricky and his Robot built a fort, which made noises that annoyed Farmer Feta, who lived next door to Ricky. When the parents arrived home, they saw the fort that Ricky and his Robot built. Ricky's mother was displeased and called the fort a mess and said that the Ricotta family is having Cousin Lucy, Uncle Freddie, and Auntie Ethel as their guests in their house. When the relatives arrived, Lucy called the fort a castle and said it should be painted pink, much to Ricky's dismay. Meanwhile, on planet Neptune, Nimrod Nightcrawler was planning to take over Earth due to their planet being cold and clouded with poisonous vapor after some greedy Nightcrawlers dug for fossil fuel which caused all of the Nightcrawlers on Neptune to live underground but he also knew about Ricky's Robot. Nimrod launched a rocket with an inflatable teleporter (wormhole) to planet Earth, which crashed at Farmer Feta's property. Through the teleporter, Nimrod convinced the Farmer that he can stop Ricky and his Robot for their annoyances by digging under his property, but the Farmer did not mean for Ricky and his Robot to be harmed. When the digging began, the fort started to tumble and when the Robot tried to keep it stable, he fell into a deep pit set up by Nimrod and his army of Naughty Nightcrawlers. After that, the fort crashed down on the Robot, trapping him. Then Ricky, Lucy, and her pets Cupcake, Fudgie, and Waffles, went through the teleporter to investigate and arrived at some underground home of the Nightcrawlers on Neptune. The Nightcrawlers in the tunnel caught Ricky, Lucy, and her pets with their tight squeeze but the heroes freed themselves by tickling the Nightcrawlers. Then they went back to Earth through the teleporter but the Nightcrawlers followed. Then the Robot got freed by Lucy who was riding on one of the Nightcrawlers' robo-suits (assumed to be riding on her unicorn as a princess) by digging him up. The Robot scared away the Nightcrawlers who followed them and made the Nightcrawlers return to Neptune through the teleporter. After that, the Robot defeated the rest of the other Nightcrawlers who were destroying Squeakyville. They, too, ran away back to Neptune through the teleporter and Ricky and his Robot jailed Nimrod Nightcrawler. Soon, Ricky, the Robot, Lucy, Cupcake, Fudgie, and Waffles cleaned up the mess by throwing away all the debris from the destroyed fort into the teleporter, destroying computers and other technology belonging to the Nightcrawlers in the tunnel of Neptune. With the deep pit in the yard, Lucy filled it up with water by a garden hose and made it into an artificial pond. The story concludes as Ricky, the Robot (using the deactivated wormhole/teleporter as his inflatable tube), Lucy, and her pets happily swam in the backyard pond.

Ricky Ricotta's Mighty Robot vs. the Unpleasant Penguins from Pluto

Ricky Ricotta's Mighty Robot vs. the Unpleasant Penguins from Pluto (2016) is a children's novel by Dav Pilkey and illustrated by Dan Santat. The 9th book in the series, it released in 2016 after spending over a decade in development hell.

Ricky and his Robot were having fun in their backyard pond until Cousin Lucy ruined the pond with pink bubble bath. Ricky and his Mighty Robot couldn't take it anymore before Ricky was upset about that and while the adults played cards, he told his parents that their backyard pond was pink and bubbly when he said mean stuff to Lucy, making her sob. Ricky's parents scolded him for saying mean things, Lucy cried before Ricky could get the change to apologize. Meanwhile, on Pluto, President Penguin felt upset that scientists in Squeakyville no longer consider Pluto a planet. Then he set off to Earth with his guards (Clancy and Nigel) together with the captain and the first mate. On Earth, Ricky and his Robot decided to make amends to Lucy. Ricky and his Mighty Robot felt bad about being mean to Lucy. Ricky tells that making amends is showing how sorry you are and since Lucy loves flowers, they flew to Hawaii to pick up some beautiful flowers and planted them on a mountain in Squeakyville so Lucy can see her name planted with flowers on the mountain. Before Lucy got to see the mountain, President Penguin's spaceship, which was shaped like a castle, landed on the mountain. Then Ricky called Lucy for forgiveness and told her to look out her window. When she saw the castle-like spaceship on the mountain with her name planted with flowers, Lucy, Cupcake, Fudgie, and Waffles ran to the spaceship, thinking it was a real castle built by Ricky and his Robot. When they approached the guards, Clancy and Nigel, the guards obeyed Lucy as their princess and baked goods for her in the "castle". Ricky and his Robot saw that three Penguin-Mobiles (operated by President Penguin, the captain, and the first mate) were invading Earth. Ricky and his Robot appeared to be no match for the Penguins, but Lucy and her pets rushed to help and they were also stopped by President Penguin, believing that he won the battle. Then Clancy and Nigel, who were showing loyalty to Princess Lucy, shot missiles at Penguin-Mobiles, destroying them. After jailing President Penguin, Lucy told Clancy and Nigel that they should be the next Presidents of Pluto so the two, new Presidents of Pluto took off with the captain and the first mate and flew back to Pluto. Since the jail was full, the expanded jailhouse was under construction. At home, Ricky and his Robot welcomed Lucy and her pets to the pond, having fun together. Ricky's parents thanked their son for apologizing and making amends to Lucy, thinking she cried of saying mean things. Again, they have a pond party while they happily swim on the pond.
