My Friends Tigger & Pooh - Season 2 Episode 33 -

Beaver's Taste Buddies: A deep, cold winter has hit the Hundred Acre Wood, freezing up Beaver's favorite food source. The trees that he normally munches on have become so stiff that he can't take a bite out of them. He calls the Super Sleuths to try to solve the problem, but begins to think he might have to move away for a while when it seems like they can't find any food that he likes.
