Boo Biscuit

Boo Biscuit is an item found in Mario & Luigi: Dream Team. It is a Boo-shaped cookie-like item. Using it in battle will make Mario and Luigi invincible for a short time. However, they will not be able to attack until the effect wears off and counter attacks will not inflict any damage on enemies at all. This item is useful if the player wants to practice countering enemy attacks. In shops, the Boo Biscuit costs 5 coins.

Trivia

 * If a Sandoon gulps a bro while a Boo Biscuit is active, it will automatically deactivate, regardless of the remaining turns and the eaten bro will be liable to taking damage while in the Sandoon.
 * If an enemy runs from battle while a Boo Biscuit is active, it will automatically deactivate and the battle will end, regardless of turns remaining.
