Tricky's Ball is an optional item that can be bought in the ThornTail Store for the default price of 15 Scarabs. The bargain price is 11 Scarabs. If used, Sabre throws the ball for Prince Tricky, calling "Go get it!" 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. Apparently, each different color change decreases the amount of a Grub Tub Tricky uses for each Tricky sidekick skills.
