Cats have retractable claws, but do any animals actually have retractable teeth or ears or horns? What about snails? Do they have retractable parts? In this activity you will create a monster with retractable ears, horns, and teeth.

ASSIGNMENT:

Your job is to alter the demo project in the following ways:

• Add two more teeth which extend down from the top of the mouth. Make sure they are spaced out evenly.
• Add two more teeth which extend up from the bottom of the mouth. Make sure they are spaced out evenly.
• Provide a number for each tooth which causes it to extend or retract.
• Add ears which extend and retract. Assign a key for each ear.
• Make horns that extend and retract. Make one key which causes both horns to extend or retract together.
