Here you will collect Spike, a mutant that’s useful once you have leveled him up. To level him up, use him either in every level you play. Also, the star level is a bonus level where you can upgrade Spike or just get a new one once he dies. Make sure you have the Spike costume, which allows you to upgrade him faster. You can face the Boss at a level 2 Spike. The boss is a level 3 Spike so make sure you have the magician suit, which increases your mojo or strength. To defeat the Boss, tap the touch screen to get your mojo going with Spike while scratching the boss a few times. Press R + Y to power hit him with a special move. You will get a gem after defeating him.
