Meat

Meat is the food that replaced Mushrooms in Paper Mario: The Thousand-Year Door during Bowser's special sidescrolling levels. Like the Mushrooms make Mario big, Meat makes Bowser bigger. They can be found by hitting a ? Block. Getting all of the meat in the level will make Bowser gigantic, allowing him to smash through everything in the level.

Interestingly, the Meat does not appear outside Bowser's events.
