Purrsephone and Meowlody are talking about Toralei and asks why Purrsephone blew up at Toralei. She says she felt left out because she was all alone. Meowlody says she feels the same way. They look down sadly just as the doors of the school burst open and flames surround the door. The two figures in the doorway announce themselves as the new kings of Monster High. They say there names are Dez and Stan. The two begin charging up the halls and plant jokes in many lockers. The twins stand up happily and meow.
Heath is talking to Billy about Abbey. Heath thinks she's overreacting but Billy says she's being defensive because she's jealous. Heath says she has nothing to be jealous about and she's overreacting. Spectra then floats in and sits next to Billy. He explains the situation to her and Spectra comes up with an idea.
Dez and Stan are sitting in study hall while the werecat twins are staring at them. The devil twins look up and wink at them. The werecats meow. The two walk over to them and sit down.
