Cat Princes

In a large house. I am a servant to two princes who are brothers, one good the other evil. They are both cats. The evil one is transporting gold and jewels to Hawaii to build a new palace. There is a creature who consumes the gold and jewels in order to transport them. The creature has no eyes or other features except a mouth set in a glassy green face. It wears heraldic costume. The good prince races around and explains the plans of his evil brother using complex gestures.
