The Monkeynator 300 is a gigantic machine that projectile shoots savage monkeys.
When the machine is activated, it glows green, and shoots out a vicious monkey. Once the monkey has it's target, it will never, ever let go until the victim's taken down.
Waffle had this weapon in his Evil Palace. It is activated by the press of a button and contains a bunch of monkeys. Mr. Blik had an unfortunate demonstration with the machine.
When Waffle's lackey, Tom, turned on him, Waffle used this machine against him, and the monkey kept Tom neutralized.
