Doc Croc is a real bookworm and the "scholar" of the pair: well-read, educated, rather reserved and a little unworldly. The practical things in life are not his cup of tea, so he is the precise opposite of Yoyo. Sometimes he can be really pedantic, but in all the adventures he is always faithful to his friend.
- Yoyo and Doc Croc first met Winnie the Pooh, Tigger, Piglet, Rabbit, Eeyore, The Eds and Rafiki in Winnie the Pooh meets The BFG.
- Yoyo and Doc Croc helped Pooh and his friends battle the villains in Pooh's Adventures of Sorcerers of the Magic Kingdom.
- Doc Croc will guest star in Pooh's Adventures of The Day After Tomorrow.
