Karel is looking for the hole where he buried his bones. If the hole is in his yard, it should be somewhere to the east. But if he gets to the house before finding the hole, that means it must be in another yard. Make Karel go to the hole and stop, or stop at the wall if there is no hole. He always starts out in the southwest corner facing east. He should end either just above the hole or at the wall facing east.

One strategy, is to make a loop that continues as long as some condition is true that can be made false at any time (such as facing a direction or the presence of a ball). If either of the desired conditions for ending the loop are met, do something to make the outer condition false:
