C.J. and Friends: All Growed Down

In this movie, The Recess Gang remembers how they all met back in Kindergarten. It begins with C.J. four of his gang looking forward to starting a game of croquet with Mickey's new set, but they needed an empty space to do so. They find a nice quiet piece of ground, and are about to set up when they are abruptly captured by Kindergartners. are surprised that they seem to no longer like the gang. The reason is that they have a new leader called Chief Squeaky who despises Big Kids and because of being bigger orders the other Kindergartners around and forces them to hold the gang as prisoners.

Desperate to be released, the gang starts telling stories of past episodes to make the Kindergartners remember how well they used to get along. C.J. tells the first story about when he encountered the Kindergartners which is from the episode "The Legend of Big Kid". After that Greta tells them the story about the "pee wee pals" from the episode "Wild Child". After that Mickey asks Chubby to remember how the two became friends in the episode "Kindergarten Derby". But despite all three stories being told, the Kindergartners are still too afraid of Chief Squeaky to admit that they remember.

After a while Rus comes outside from the nurse's office and starts looking for the gang, only to get captured as well. To convince Harold (the Kindergartner in pajamas) about how he was his "safety man", he tells a story about when he first went to Kindergarten. At first the other gang members remind him that he did not come to the school until the gang was in 4th grade (an allusion to their memories in the episode "The New Kid"), and besides, none of them even want to think about when they were savage Kindergartners. But Gus points out that long before, he briefly had been a Kindergarten student.

In his story, his parents bring him to 98th Street School. Rus is a wild child and thinks that the other students he meets will be just like him, but to his surprise, everyone is acting well behaved in class, and Mr Boyd reads them a story. When recess begins all the children are quiet and nobody acts like they do in the future. Rus notices Greta just reads and never gives anyone ideas, Vance just runs around quietly, the Diggers just play in a sandbox, Swinger Boy and Upright Girl do not swing roughly or hang upside down, and Rigalli is a timid little girl with a doll. Rus then meets one little girl with a blue cap whose name is Carolyn Jessica Rotweiler. Rus befriends her and gives her her nickname: C.J.

Shortly afterward, Rus realizes that everyone is being neat and behaved because they are afraid of Mickey who acts as a monstrous bully, and Rachel is the one who tames him. Rus is enraged and he later reveals the reason that Mickey acted like a monster is because Rachel told him lies and said she was her only friend. Mickey is actually friendly and explains that Rachel was behind everything because she wanted to take control of the whole grade and have everything belong to her.

Then Rus convinces all the Kindergartners that they should be like him and be wild like a normal Kindergartner, then all the kid begin to act like their future selves, Vance becomes more active, Greta starts passing her theories to other kids, Rigalli realizes that she is a very tough girl, and C.J. becomes brave and adventurous. Rachel is horrified and quickly tells Mr Boyd that everyone is all messy. Mr Boyd is furious and demands to know who did this. When he finds that it was Rus, he takes him to Principal Prickly's office. However, C.J. and the gang form a plan and rescue, Rus, leaving Rigalli's doll in the chair he was sitting in. Rus is forced to leave the school the next day.

After he finishes his story, Rus tells Harold that he and all the other Kindergartners should stand up to Squeaky. So Harold trips Squeaky, making him cry and as the others rejoice, Captain Picky makes Harold the leader. The Recess Gang is then released. C.J. and the gang tell Rus that he was very clever to make up such a story, Rus agrees that he just imagined it all and then the gang starts to spend the rest of the recess having fun together.

However, Mr Boyd who is watching, tells Rachel to keep an eye on Rus, and then vows that someday she will get revenge, hinting that Rus' story was true, after all.
