For Enzo, the Fourth of July means three things: fireworks, family, and car races! This year Zoë is finally old enough to compete in the Kids' Kart Challenge. But when one of the boys at the track says that girls aren't fast drivers, Zoë gets nervous and backs out of the race. Enzo knows it's up to him to help his family regain the confidence to compete on the big day.

Mutt Enzo shares his first Halloween with Denny and Zoë while dressed as a ferocious dragon protector in a neighborhood transformed by jack-o'-lanterns, giant spiders, and graveyard front lawns.
