Waking up from a nap in the Hundred Acre Wood, a puzzled Winnie the Pooh has the feeling he's forgotten something important and somehow arrives at the idea that it must be Eeyore's birthday. The player follows Pooh in his journey around the Wood to spread the news, dropping in on Kanga, Tigger, Owl, Piglet and Rabbit and helping them prepare a party through various activities and minigames.
