When someone makes a mess of the garbage cans, Buster and Phoebe are determined to solve the mystery of the Garbage Bandit! Meanwhile, Buster's bones have mysteriously disappeared, so he and Phoebe are on the hunt to find them in the backyard.

Buster, a very shy dog, does not get along with the other pets in Roger's house, especially bold and popular Phoebe, but soon Buster discovers his own special talent.

A clever dog named Phoebe teaches the new puppy, Buster, the value of bones and how to train them to "stay" so that they do not disappear when he leaves the room.
