raptorboy, there was a white banshee there at first so nothing worked then i went to the third hero's house, knocked on his door, went back down there and it was the red banshee. then i could kill it. i don't know if it was a glitch or what but what you told me worked on the red one so thanks.
yeah they're gargoyles. its actually a quest called gargoyle treasure and they're just gargoyle heads on walls of random places and you shoot them. anyone know how to kill the banshee that sam and max release cuz nothing i do effects it and i cancelled the quest but its still there and i can't continue with the main storyline till its dead.
