During the shot of Mr. Creosote inflating, some of the extras on the right hand side of the screen can be seen behind him. After the explosion, many of the same extras can be seen in one shot being hit by Mr. Creosote's entrails, but once the explosion is clear, they are again behind him, but free of any of the viscera that they were previously splattered in.
