Pooh wakes at sixteen o'clock... Piglet visits him and he's just in time for a smackerel. Pooh finds a tooth among his marbles. Piglet and Pooh go to Rabbit. It's not an eye tooth or a nose tooth - Rabbit tells him it's his sweet tooth! Pooh is horrified - he can't eat honey without his sweet tooth. Rabbit tried to tie the tooth to Pooh... He plants it nest to his sweet potatoes and sweet peas... But he digs to deep and it falls into Gopher's tunnels. To make matters worse, the tooth is taken by Pack rats, along with some of Gopher's tools leaving their trademark walnuts in place. The robbers are making their way through the 100 Acre Woods, and try to take a sundial. Owl comes to them and talks about yet another member of his family and takes the pretty doorbell (Christopher Robin's tooth). Pooh goes to Owl's house and sees it and sees his familiar looking tooth, but it' taken by the Pack rats again. Rabbit accidentally drops Piglet into the Pack rats loot sack. The rats take off with Piglet, Pooh's tooth and Gopher's goodies. They run into their lair and place Piglet in the armor of a knight. They place Pooh's tooth in their chattering Tooth toy, but are disappointed that it's too small. Pooh is looking for Piglet. Gopher gets Piglet out of the knight and they are upset that they can't seem to find the tooth. The Pack rats want Pooh's watch. Pooh says he'll trade it for his tooth. The Pack rats huddle and then say that if Pooh can guess where his tooth is, he can have it. Pooh says the last place he would look is behind the Pack rat Leader's back because that would be cheating, and that's just where it is! The Rats give Pooh back his sweet tooth. Pooh tells his story. Chris t his story. Christopher Robin tells him that Pooh bears don't have teeth and if they did, Pooh's sweet all over! He tells Pooh that the tooth is a baby tooth he hid with his marbles. He gives it to Pooh and the Tooth Fairy gives him a pot of honey - much better than walnuts!
