2010: MyX "Revenge Rocks!" was the 11th edition of Howl-O-Scream to take place at Busch Gardens Tampa Bay.
The theme of this year's event concerns the evil rocker Sylvie and her band MyX. The character's backstory is that she caught her boyfriend with another woman. Wanting revenge on him, she lured him backstage and cut off his index finger and collected it in a vile. She now continues this practice by choosing a man out of the crowd during each MyX concert and collects their index fingers in viles which are hung in her backstage dressing room.
