He first appeared in The Many Adventures of Winnie the Pooh, fixing Eeyore's tail on. He then helped Pooh in his quest for honey by giving him his blue balloon. However, Pooh realized these bees where the wrong sort, so he fled when the Queen Bee threw him away. He later helped pull Pooh out of Rabbit's front door.
When the Hundred Acre Wood was flooded, Christopher Robin's House couldn't be flooded, so Kanga, Roo, Tigger, Rabbit and Owl went there, while Eeyore stuck to his search of house-hunting for Owl. When Roo found Piglet's note, Christopher Robin sent Owl to find Piglet and after Pooh saved Piglet, Christopher Robin gave him a hero party. In the middle of it, Eeyore revealed he had found Owl's new house: Piglet's House. Piglet let Owl take his house and lived with Pooh. Christopher Robin also helped get Tigger down from a tree.
In The New Adventures of Winnie the Pooh, he lives in a different house with his mother and goes to school. He first officially went to school in Pooh's Most Grand Adventure, at the end of summer and at the begining of autumn. He failed to tell Pooh he was going to school and Pooh failed to notice his notice that he was going to school, so when Owl read it, he made it seem he was going to Skull Cave. Pooh, Piglet, Rabbit, Eeyore and Tigger eventually found out Christopher Robin's true note and met him eventually, so Christopher Robin could once again go to school.
