In order for Courage to grow he needs to eat 3 meals a day. At each meal help Courage collect all the bones while avoiding the scary monsters before the timer runs out. Once you have collected the last bone, hurry home and bring them back to his doggie bowl so he can eat. If the timer runs out before you get to the bowl or a monster gets you, you will have to start the level over.
