During a Kiss concert that Meltman and Thundergirl are attending, the noise caused by the band awakens a gigantic baby wearing nothing but a diaper. Big Baby, as it's known, enters the concert scene and runs rampant, eventually gnawing on the band members due to its teething. Can Meltman, who earlier claimed to be personal friends with Kiss, do something to stop it? (First appearance of Big Baby. Guest voices done by the members of Kiss. This episode was shown in theaters before Good Burger.)
