One morning, Grug wakes up and decides to become a superhero. Wearing a cape and a mask, and a sword made from sticks, Grug and Cara, his best friend, transform the Grugmobile into the Zoom Zoom Car and head off to save someone. But the Zoom Zoom Car has too much zoom and Grug and Cara discover that if they can't save someone else, they can at least save themselves.
