The grouchy Mr. Grumps finds Lyle a nuisance because Lyle scares his cat, Loretta, and he has him thrown in the zoo. When Lyle is freed by his old performing partner Mr. Valenti, they go back to the house on 88th Street, where they find Mr. Grumps' house on fire. Lyle rescues Mr. Grumps, is declared a hero, and thus is allowed to stay with the Primms.
