The Tigger Movie (2000)
As we join our favorite cuddly friends, Winnie the Pooh, Piglet, Owl, Kanga, Roo, Rabbit, and the ever-exuberant Tigger, the whole gang is busy preparing a suitable winter home for the delightfully dismal donkey, Eeyore. Everyone's helping except Tigger, whose boisterous bouncing interrupts their efforts. When Rabbit suggests Tigger should go find other "tiggers" to bounce with, the notion seems absurd because he thinks he's the only one. But is he? Tigger begins an amazing journey through the 100 Acre Wood looking for a family of tiggers. -- © 2000 Walt Disney Pictures
