Kibo

Kibo used to be a baby tree who was found by Nobita when he went searching for his test papers. Nobita, than 'thanked' the tree, and in exchange he decided to plant him in his yard. Nobita requested for Kibo to be made 'human' to which Doraemon thought would be a good idea. He and Nobita became good friends, and Nobita introduced him to Shizuka, Gian and Suneo.
