Christopher Robin is one of Pooh's best friends. He led an Expotition to the North Pole and he comforted Pooh when he was stuck in Rabbit's hole.
Christopher Robin gave Pooh many of his titles (silly old bear, helping bear etc.) and he had a party in his honor. He likes to play Poohsticks and he helped to rescue Piglet from the flood.
Christopher Robin takes care of his friends, like when he rescued Piglet or when Kanga and Roo came to the Forest he was their first friend.
