This poor ape needs a dentist, and you are just the person for the job! When the ape opens his mouth for the first time, you will see several teeth that are green and rotting. These are the teeth you need to pull. He will then close and reopen his mouth. When his mouth is open the second time, you will no longer see which teeth are green. You have to rely on your memory! Click and pull the decayed teeth. If you try to pull a healthy tooth, the ape will clamp down on your hand, and you'll have to start again.
