Harley’s Humongous Adventure Super Nintendo game cartridge. Harley is a cool young genius whose biggest experiment just backfired in a most heinous way. Something went wrong with Harley’s shrinking machine. Now he’s bug sized and the machine blew up. Bogus! Now Harley has to search for the missing parts of his machine. He’ll have to run, jump, swim, climb, fly with a jet pack, look for weapons and fight mutant bugs.
