Escape from Leprechaupolis.Dr. Weird builds a machine which shoots massive rainbows that can grab people and throw them violently, but it is mysteriously stolen during a blackout. The culprits are three leprechauns, who concoct a nefarious plot to send people e-mails promising gold if they go to a local park and step into the rainbow; the rainbow then sucks up the victim, where the leprechauns can mug them for their "treasure" (even though they mostly steal junk and shoes). The Aqua Teens get involved when both Frylock and Carl receive the phony e-mails; Carl falls for the trick and has his gold chain stolen. Eventually, Frylock defeats the leprechauns with his eye lasers, while Meatwad delivers a bizarre speech about rainbows not being made from rainbows, but "happy thoughts, dreams," and various candy.
