It seems it's always summer in the Hundred Acre Wood, and all the forest animals are having a great time. All, that is, except poor old Eeyore. He's so old and sad, he can't even remember when his birthday is. Now, Pooh's known as a bear of very little brain. But he has a simply splendid idea - a plan that'll surely cheer up the gloomy old donkey - a surprise party in his honor. But presents must be found, and it's not going to be easy to pull that off without Eeyore finding out about the party. Every animal in the Hundred Acre Wood is about to learn what caring and sharing are all about!
