Continuity mistake: As Fat Albert's gang is trying to get the football from underneath the building. A rival gang member gets stuck in the small hole. The shoe color of the fellow gang member, Kong, who pulls him out, changes from white to yellow, as he is pulling the guy out of the hole.
Continuity mistake: Just after Otis makes the ghost sounds from inside the house, it shows the gang standing together outside the house. Otis is with them outside, which is impossible, as he is inside the house pretending to be the ghost.
