How do you beat sgt. crushida pepper in papa louie when the pizzas attack

You notice those two pizza monsters under the conveyor belts in the battle room? Well, when Sgt. falls off his high platform (this is indicated by him saying "whoa") hit the cheese from one of the monsters at Sarge and if the cheese hits him, he should become immobile. This is your chance! Throw a pepper bomb at him and if it hits, he will lose one health. Don't try peppering him when he is not cheesed, because he will just hide under his helmet. Repeat until he is dead.
