Swing and Bounce are two trapeze children that perform in the pre-show. They have a very small part, but Joker takes care of them like a mother. The two of them are twins so their voices don't have to be too different, though they have slightly different personalities. Both are bubbly and happy, but Bounce is more Naive than Swing. Neither of them truly know what's going on with the main show, or that they're being used as blackmail.
