Things in the Castle have been mysteriously left in pieces, and Wizard tells Bo the culprit must be the Pull-Aparter, who simply loves to see how things are put together. To find the Pull-Aparter, Bo and Dezzy first sneak like a Spider to get past a suspicious meerkat, then pounce like a Puma to gather pieces of a door from some busy beavers. Inside the pulled-apart world of the Pull-Aparter, Bo and Dezzy make a present of a Builds-Anything Beaver to him, so that anything pulled apart is immediately put back together again!.
