"A Pest of a Pet" is the tenth of the thirteen episodes from The Wuzzles.
The Wuzzles get revenge on Rhinokey by playing a joke on him that makes him depart from Wuz.
When Rhinokey decides to play a trick during Hoppo's audition for the ballet "The Diving Swanpig", the other Wuzzles manage to get a mockingbird-dog (part mockingbird and part dog) to teach him a lesson. When he tries to hide from his new pet, he gets laughed at by his friends and feels ashamed about it and runs away.
Suddenly all the mockingbird-dogs get loose and raise havoc in the Land of Wuz. The Wuzzles realize that Rhinokey is the only one who can out mock the mockingbird-dogs and convince him to come back. Rhinokey finally manages to capture all the mockingbird-dogs, but also plays one last practical joke on Hoppo.
- The theater that Rhinokey hides in is showing the movie "To Kill A Mockingbirddog", a spoof of the 1952 Gregory Peck movie "To Kill A Mockingbird".
