Monstercise

The only known version of Monstercise is rather incomplete, and much like Grovers Music Maker, there's actually very little gameplay involved. The screen displays a group of monsters doing what appear to be Jumping Jacks. At the bottom of the screen is a blue blob (which is assumed to be Cookie Monster) holding a spotlight. Pressing the # or * buttons on the Kids Controller will cause Cookie Monster to move left or right, and when you get underneath a monster the spotlight will shoot a beam and highlight the monster. Once the monster is highlighted, you can control his (its?) head, arms, or legs by pressing the the keys on the keypad. Each body part seems to have two different actions (three if you count not doing anything). The head can blink or nod up and down, the arms can either flap or pump up and down, and the legs can kick out or squat. After awhile the whole thing begins to look like a creepy exercise video, which may be where the name came from.
