Revealing mistake: Uncle Ghost sets a headstone in front of Ricky and tells him to break it with his energy. He breaks a small corner on the headstone with his hand to demonstrate, however it can be noticed that there are visible cut marks on the corner that he breaks off before doing so, revealing that the corner had already been cut off and reapplied to make it easier for Uncle Ghost to chop it off.
