The Happy Helpers get called by Mr. Bigby to be pet groomers for the Hot Diggity Dog Show hosted by Robbie Roberts when the appointed groomer Caesar Du Flan gets infested with fleas. The dogs they must groom are Pluto, Butch, Mr. Doozy's dog Wanda, and a dog named Champ, whom Mr. Bigby is watching for Ivy Beaglesnoot, who broke her toe and can't be there. But things go wrong when Jinx gets into Corn Dog Stadium.
