I have an idea barrells for bosses floating Stephan for power ups yellow and red the yellow ones could give his the ability for super sonic shreak and the red one makes him go full swedish and has the ability to beat up barrels with his bare hands. and each boss level you beat you gain a new youtube character with the own special ability like if it pewds his ability would be the bro fist and say cinnamontoast ken he would use a cinnamon stick to beat the barrels and
