One day, the Simpson clan is strolling through Springfield, when all of a sudden Homer bumps into Mr. Smithers, who is stealing a diamond from Springfield Jewelers for Mr. Burns. After dangling in the air for a few seconds, the diamond takes the place of baby Maggie’s pacifier, and Smithers kidnaps her. The rest of the family takes it upon themselves to rescue Maggie, fighting tons of mooks, Smithers, and Mr. Burns himself in the process. Such is the plot of this well-received, licensed arcade Beat'Em Up released in 1991 by Konami, based on The Simpsons.
