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.
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.
Plot hole: Dumb Donald chooses not to play hookey with the rest of the gang. He instead goes to school. The gang is even worried Dumb Donald may, "Rat them out" to the school. Yet throughout the episode, Dumb Donald appears/disappears with the gang as they are skipping school.
