Lazer Gun

The Lazer Gun is an item that can be given to monkeys, not buildings, during a game. It costs $40MM and can be used on any monkey with a free arm. Monkeys with free arms can be placed the Lazer Gun on its hand, and fire beams at 1 beam per 2 seconds and can pierce 6 bloons while dealing 3HP damage.

Non-robotic super monkeys actually have 2 free arms since their attacks rely on vision, so you can place 2 Lazer Guns on their hands and they would still be able to fire. However, you cannot use them on the Temple of the Monkey God.
