Actualy, I beat conveyor belt zomboss and that is enough for me. I'm halfway to kernel pult costume! For different types of Zomboss battles: Easy (Conveyor belt), Medium and Hard (Last Stand type levels), the game gives you different puzzle pieces. Easy: 2, medium: 4 and Hard: 8. Play on hard. You can unlock each costume faster.
