It is a brown square.Its everything was like racer but its speed was sightly slower. That special that there are TWO twins one time when you use it.One is still control by mouse and one is control by arrow keys.That mean you will have two life and the twins can attack others together.
If the two twins finished the laps together, you still only finished one lap. If only one twin finished the lap, you will be finished one lap.
