Tricky's Ball is an optional item available in Star Fox Adventures. It can be bought in ThornTail Store for the default price of 15 Scarabs. The bargain price is 11 Scarabs. If used, Fox throws the ball for Tricky to fetch it. Playing with him for long enough will cause a change in Tricky's coloration. The color changes in a cycle, from purple and yellow to pink and purple, and then to aqua-blue and lemon-green. Nothing else is known to be achieved by doing this.
