We want the Bone class once it is touched by the Dog class to pile up the bones in the right corner of the World.

You want to add a new state to the bones. The state of being collected or not. States are described by fields. Since there are only two possible states for collected (being or not being), a boolean field is in order. After line 43, add code to check for an intersecting Dog object. If found, find a place in the corner for the bone and switch the boolean value. Since the bone must cease and desist in this state, add the following at the beginning of that act method:

if (collected) return;
