I own a chinchilla, but I'm sorry to say that I can't help Ты with that one.. My Chinchilla is very tame and isn't very active. He likes it when I hold him, and pet him, and he's always ready to run outside of his cage, through the house. But that's just him, I'm sure that not all Животные think the same way.
Maybe if yours is playful, it'd like some bells или something? Mine isn't very playful, but it still likes playing with bells. (Sorry, I'm not very good at chinchilla-advise XD)
