Bart Simpson has discovered that mutants have a machine to enter ingredients which will allow them to conquer the Earth. Bart goes in search of these ingredients to hide them or to take them, avoiding disaster. His adventure will take him across an amusement park, the shopping mall, and the museum, to name a few.
