Tommy wants to win the DeSpray Bay Math Olympics and defeat his nemesis, Melba. Unfortunately, he stinks at Math, but Gumpers is a mathematical genius and Dinko owns a Conforma Brain Beanie that can transfer Gumpers' thoughts into Tommy's brain. Victory is only one question away! / When Tommy's too busy studying to play soccer with Dinko, he does the next best thing - he creates a duplicate Tommy by hotwiring a photocopier with extra power. Then Dinko decides why stop here? If two Tommys is twice as much fun, how much fun that three Tommys be? Or four? Or even many, many more!
