When Chomper's cousin Slick (Macaulay Culkin), a pool-playing master, comes to Wanda's refreshment shop, he beats everyone in Pool by secretly cheating. Rainbow, unaware of this at first, is in awe, and decides to become his assistant, then discovers his secret. Rainbow then declares a match to determine that Chomper's relative is cheating. Rainbow then wins, and the other player leaves the shop forever.
