'''Boo Biscuits''' are [[List of items|items]] in the ''[[Mario & Luigi (series)|Mario & Luigi]]'' series introduced in ''[[Mario & Luigi: Dream Team]]''. It is a [[Boo]]-shaped cookie item, that will turn [[Mario]], [[Luigi]], [[Bowser]], and [[Paper Mario (character)|Paper Mario]] [[invisible]] when used in battle, rendering them invincible for a short time, similarly to the [[Repel Gel]] and [[Boo's Sheet]] items from the [[Paper Mario|first]] [[Paper Mario: The Thousand-Year Door|two]] [[Paper Mario (series)|''Paper Mario'']] games. It affects all characters at the same time.

Users are unable to take any actions until the effect wears off. Additionally, all [[counterattack]]s will not inflict any damage on enemies, including those where the enemy hits itself. This item is useful if the player wants to practice countering enemy attacks, or to complete dodge-focused [[Expert Challenges]]. In [[Item Shop|shops]], the Boo Biscuit costs 5 [[coin]]s.

In ''Mario & Luigi: Dream Team'', Boo Biscuits last for three turns, and cannot be used if one brother is unable to act due to a status effect. The effect ends when the brother who used the item gets the chance to act.

If a [[Sandoon]] swallows a brother while a Boo Biscuit is active, it will automatically deactivate, regardless of the remaining turns, and the eaten brother will be liable to taking damage while in the Sandoon. Further, if an enemy [[Flee|runs]] from battle while a Boo Biscuit is active (i.e. a [[Beehoss]] without any bees left), it will automatically deactivate and the battle will end, regardless of turns remaining, unless there are more enemies in the arena. Using a Boo Biscuit when [[Pi'illodium]] prepares to perform a fire wave attack will void the fire wave.

In ''Mario & Luigi: Paper Jam'', using Boo Biscuits in the battle with [[Nabbit]] will cause them to immediately wear off and Nabbit to run away. Boo Biscuits are also disallowed in the battle against [[King Bob-omb#Mario & Luigi: Paper Jam|King Bob-omb]], due to it having a timer.

Boo Biscuits also appear in ''[[Mario & Luigi: Superstar Saga + Bowser's Minions]]'' and ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]''. In the former, 30 Boo Biscuits can be obtained by fleeing 10 battles and speaking to [[Miles Tones]] in the [[Information Booth]].

In ''[[Mario & Luigi: Brothership]]'', Mario and Luigi no longer become transparent when using Boo Biscuits, though they are still invincible during the duration. This, alongside the Protectus [[Battle Plug]], is also the only way to dodge the fire waves that the [[Extension Corps]]'s members use in the final leg of their fight; otherwise, only the [[Guard|Emergency Guard]] is available for damage reduction.<ref>{{cite|url=www.youtube.com/watch?v=-T_XoHVq8xQ|title=''Mario & Luigi: Brothership'' - All Bosses + Secret Bosses (No Damage)| timestamp=1:22:24-1:22:41|author=NintendoBase|date=November 6, 2024|publisher=YouTube|language=en|accessdate=January 8, 2025}}</ref> During the [[Monster Mania: Level 4]] [[List of Mario & Luigi: Brothership side quests|side quest]], Boo Biscuits cannot be used as the challenge involves dodging [[Bob-omb]]s that can otherwise one-hit KO the Bros.
