Joe, Farina, and Harry are racing their dog-powered cars when they are stopped and reported to the President of the Be Kind to Animals Society. After promising to be kind to animals, the boys are made honorary society members. They soon convince other children to be kind to animals, and they release them from their cages to ensuing chaos.
The wide street where the Gang are racing their dog-powered cars is the 3300 block of Motor Avenue in the Palms district of Los Angeles.[5] Hedda Hopper gets out of her parked limousine in front of 3392 Motor Avenue.[6]
