One day, Kanga and her baby, Roo, arrive in the woods, which puts Rabbit on edge because he doesn’t like new animals just appearing. He devises a plan to make them leave that involves Pooh distracting Kanga so that Rabbit can take Roo out of Kanga’s pouch and put Piglet in his place. Then, when Kanga asks where Roo is, they’ll say, “Aha!”, meaning “we’ll tell you where Baby Roo is, if you promise to go away from the Forest and never come back” (93).

The three find Kanga and Roo in the forest, where Kanga is watching Roo jump. Pooh tries reciting poetry, but when that doesn’t catch Kanga’s attention, he tells her to look at a bird in a tree behind her. When he does, Rabbit grabs Roo, while Piglet hops into Kanga’s pouch. At home, Kanga realizes that the group switched Piglet and Roo, and she decides to play a joke on them, pretending Piglet is actually Roo. She gives Piglet a bath, scrubbing him clean.

Christopher Robin arrives to say that Piglet is definitely not Roo but that he doesn’t know who he is (not recognizing him because the bath cleaned off all the dirt).
