Snake Rattle N Roll - (Complete) Nintendo NES

It's a race to the moon for the two snakes, Rattle and Roll! Play alone or simultaneously with a friend as you out-score and out-eat your opponent - then weigh yourself on the scales and make for the exit!

Snake, Rattle 'n Roll is an isometric 3D platformer. The object of each level is to eat as many Nibbley Pibblies (round creatures of various colours) as possible to make your snake heavy. Once it's heavy enough, you must stand on the scales in the level, and if you're heavy enough, the door will open and you can make your way to the exit.
