The Great Time Travel Adventure part 105 - NightoTerror

The Villains have made thier next schemed move now. But things go bad to worse when Marcline's Dad probes X's mind of his knowledge and then gives the heroes something to fear when he sucks Morcedai and Rigby's souls dry.

Nibbler, Lizbeth, Pinky and Brain are all musing that MD has a trick up his sleeve for them all and that no one really knows what the human/ abomination demon is up to.
