Sean Wissler

Sean Wissler is one of the developers of 5th Cell, and is a creatable character in Scribblenauts. He is afraid of everything living, and will run away if he sees someone. Despite being an Ooze, albeit a light blue one, regular oozes will still attack him. He also happens to be invincible, meaning the only way to kill him is with an instant kill, such as Death or a Black Hole.
