Its Benny's first-time trick or treating. His mommy dressed him in a skeleton shirt, she dressed him this way for easy diaper changes. She says come on little one be brave; it's your first time trick or treating. They'll give you candy, just knock on the door. Benny nervously knocks on the door, trying to be brave for his mommy. The promise of free candy helps him be a brave cub.
