If you pres R4 he talks. If you press the oil can R4 will drink, if you press the battery it will charge (substitute for eating) if you press the ball he will shoot a hoop and if you press the light he will dance, but click the green flag after to reset after the animation finishes for the dance so it resets. Charge=Battery Oil=Gas can thingy. If he says he needs it, he doesn't really, but it makes it fun. Don't (you could...) click space
