Winnie-the-Pooh and Me

Someone has come along to join Winnie-the-Pooh and Christopher Robin on their adventure, but who could it be? It can't be Kanga and Roo - they're sailing a boat - and it can't be Owl, because he's at home. Could it be Heffalumps who want to eat Pooh's beloved honey? Or perhaps Pooh and Christopher Robin are accompanied by a pair of friends who are never far away on a sunny day.3+
