Mr. Whiskers brings home a small pet rodent after accidentally destroying its habitat during a game with Ed. However, Brandy is skeptical because Mr. Whiskers' previous pet parakeet and fish both died due to his negligent nature, though she decided that she'll give Mr. Whiskers one last chance in seeing if he can be responsible enough to take care of the rodent. However, when Mr. Whiskers falls asleep with the tree house door open, he frantically searches for the rodent in hopes of bringing it back before Brandy notices his absence.
