As the episode opens, Grundgetta is playing with her Rottendoodle, Itchy -- a flea-ridden Grouch dog that does absolutely nothing she asks it to do. Oscar asks where he can get a Rottendoodle of his own. Grundgetta calls the breeder.
Mr. Blechstein, the breeder, makes sure Oscar will provide a grouchy home for his new Rottendoodle. After being shown that he can, Blechstein gives Oscar a book about pet care & the leash to his new pet, Cranky.
