Steak and Jake are friend and co-workers. Their task is to deliver a milk on the right place and not break the bottle. The milk is in Steak's hand and Jake does all the work around. He must make clear way for Steak. You must search for the same color marbles and when you have enough of them the place that needs them is filled and Steak can continue walking. Same thing is when you destroy enemies. Sometimes you help Stake by transporting him into higher or lower ground.
