Shivers 2: Harvest Of Souls

Hint: Bakery: Chinese circle puzzle :
Click on gears until you can create the circle. Note: You do not have to end up with the circle in the center of the square grid. The puzzle is solved easier by having the circle formed in one of the four corners of the grid. Experiment by clicking alternate gears repeatedly and watch how the circle quarters shift across the field of the grid. This should give you a clue as to how to proceed.

Hint: Bakery: Kachina donut puzzle:
After picking up the phone messages, go to the bread oven in the back and click on the lever. Then, click on the oven door to see a strange Indian mask inside. Click the mask to get the rules for the ten hopping donuts puzzle. Assign numbers to the donuts from left to right as follows, with "O" indicating a donut.
