In the Hundred Acre Wood that makes up the imaginary home of several toys owned by Christopher Robin (voice of TOM ATTENBOROUGH), Tigger (voice of JIM CUMMINGS) is a happy tiger who not only enjoys bouncing about on his spring-action tail, but also the fact that he's the only Tigger in the world.
Yet when he realizes that his friends, Winnie the Pooh (voice of JIM CUMMINGS), Piglet (voice of JOHN FIEDLER), Eeyore the donkey (voice of PETER CULLEN) and his best pal, Roo (voice of NIKITA HOPKINS) the young kangaroo, don't have time or can't join in his bouncing ways, Tigger begins to wonder if there are any other creatures like him who can.
After a search through the woods and an inviting letter prove to be fruitless, Tigger becomes depressed. As such, Roo, along with his mother Kanga (voice of KATH SOUCIE) and the wise old Owl (voice of ANDRE STOJKA) decide to cheer up his spirits by answering his letter and even dressing up like other Tiggers.
Tigger eventually catches on to their well-meaning plan and then sets off through the dead of winter to find the family members he's never met. As his friends become worried about his whereabouts, they finally persuade Rabbit (voice of Ken Sansom) to head a search party for their friend, who will soon learn that his real family has been right under his nose all of this time.
