|This is a mixture of a standard chess set and a Super Mario Brothers chess set.|
After they had been playing for a while, a third player joined in. Can you spot the grasshopper?
The kids decided to embrace the grasshopper's participation and made up some rules. 1) If the grasshopper was perched on a playing piece, that piece was invincible. 2) If the grasshopper was perched on an unoccupied square, no piece could move there.
