A great old arcade game originally made by Data East. Became popular not only in the arcades, but on the Intellivision, Colecovision, and Atari systems. Even got translated to the NES back in the day.

The player assumes the role of a chef who must create gigantic hamburgers with lettuce and tomato. To do so he runs over the burger/lettuce/tomato. The piece then falls a level and knocks down the lower pieces. If any enemies are on that piece, they fall to their death and bring down the piece with them (to the bottom of the screen, which is the objective). If any enemies are below, they are squished and respawn after a few seconds. The enemies are eggs, hot dogs, and pickle slices. The eggs and hot dogs can only walk on the ladders and platforms that you may walk on. The pickle slices can float around to chase you. The player is armed with a pepper shaker and may use it to temporarily paralyze his foes. He starts off with 3 lives and 2 peppers.
I highly reccomend the Intellivision version myself as it has the best balance of graphics and gameplay.
