LUNCH BREAK is a downloadable microgame in WarioWare: D.I.Y. and WarioWare: D.I.Y. Showcase. It was released in America on May 17, 2010. It was made by Alison, one of the two hosts of Nintendo Week. The microgame is based on the episode where Dark Gary stole Alison's lunch.
The game starts off with three hats (Wizard's hat, Chef hat, and a Witch's hat). The player has to tap Dark Gary's hat to see Alison's lunch and win the game. If the player taps the Wizard's hat or the Chef hat, the game automatically ends in a loss.
