During the morgue cutscene in Arkham Asylum, the player has to investigate three body bags. It doesn’t actually matter what order you open them in, all three contain the same character until interacted with. The first bag will always be Tomas Wayne, followed by Martha Wayne. Finally, you’ll be greeted with jump scare when the Scarecrow pops out of the third body bag.
But you want to know the best part of all this? For just one single frame while opening Martha’s bag, Scarecrow’s model pops into the scene standing completely vertical with his head spilling out like twinkie filling.
