A strange talking Bakugan jumps on a bird in the beginning of the episode as Dan and Runo talk to the others about some odd construction going on in town. It turns out that this place is Marucho's house, and he's finally moved into Dan's town. After Julie gets jealous that she was not invited to Marucho's home, Runo claims she forgot. Dan takes this opportunity to tease her and call her a scatterbrain. As a result, Marucho watches them bicker with each other. He starts giving them a tour of the huge mansion when they run into the mysterious Bakugan, whose name is Preyus. In the meantime, Masquerade is back again and gives the pop idols Jewel and Jenny Doom cards. They then crash Marucho's party and challenge Dan and Marucho to a combination battle. Preyus manages to pull out a few tricks and set the battle in their favor.
