Cheezy Poofs

A box of cheese flavored puffs. It weighs 1 pound and costs $5.

This item can be given to a giant talking mole rat, Brain, under the Gecko Junkyard.

Background
They're yummy, they're nutritious (well sort of), and they last forever without going stale - they're scrum-diddle-icious Cheezy Poofs, and giant mole rats just love 'em.

Behind the scenes
The South Park character Eric Cartman's favorite snack of the same name is a likely reference to this item.
