A young imagination is bold, likes to make bigger leaps. It likes to, well, imagine that the dustbuster is a dinosaur that the computer mouse is a hotrod that the box is a cave that the rawhide is a torch... or a baton... or something.

Rocca is describing the distinctive freedom of childhood creativity: young minds readily transform ordinary household objects into props for elaborate stories. The “bigger leaps” are imaginative associations unconstrained by practicality or adult categories—turning a dustbuster into a dinosaur or a box into a cave. The trailing “or something” underscores how improvisational this play is: the point is not a fixed metaphor but the fluid ability to reassign meaning on the fly. Implicitly, the quote also contrasts adult perception—literal, utilitarian—with a child’s capacity to animate the everyday, suggesting that imagination is a kind of cognitive boldness that can be nurtured or lost over time.
