How to consume food: Press space to open your mouth. Apples are really tasty, so get as many as you can. Bombs taste bad. Don't eat them. Pineapples are tasty, but they're very spiky so don't let them touch you. Watermelon rockets have two ways to be approached. If the watermelon side is facing you, then eat it. Be careful, as if you don't the rocket will stab you. If the exhaust is facing you, do not eat it. Motor oil tastes bad. On top of exploding, it will serve as valuable damage to bosses. Watermelon seeds must be consumed. Under normal circumstances, they are not dangerous, but the watermelon boss hurls them at you with such speed that the only safe way to dispose of them is through your mouth.
