Chapters 1: An unexpected turn of events

This maybe a parody to The American werewolf in London but with a twist. So here's the plot; Pearl wins the splatfest for Vampires vs Werewolves, and Marina, this time, overreacts. And decides to have an argument about it with Pearl at home, so Pearl kicks Marina out for the night, and wants her to apologize for overreacting to a splatfest the following morning. However...something happens to Marina that night and she goes back to Pearl and apologizes for overreacting and all is good, until everything changes when the next month arrives...something monstrous comes out from Marina on the night of a full moon. Will Pearl survive the nightmare or will she become dinner for the monster?(Cliffhanger dun dun DUUUUUUUN! I think we all know what will happen and btw)
