Crabtron

Crabtron is a space-age video game featuring Slab the Crab. It was created by Hasbro and engineered and disributed by Namco in the early 1990s. While the original quality of the graphics has been disputed by some (due to the varying bit rate), it is generally played during moments when one has absolutely nothing to do.
