Continuity mistake: After the hands draw the concert hall, the lion conductor walks out on stage to address the crowd. He stops in the center of the stage and turns, facing straight forward towards the camera. But then it cuts to a close up and suddenly his body is facing to the left. You can also tell by his shadow that he is suddenly much closer to the curtain behind him. (00:01:35)Quantom X
Continuity mistake: When Goodwill captures the pigs (except for Porky and Petunia), there are "X" marks on the couch. When Porky and Petunia walk past the couch to look for the four other pigs, the "X" marks have gone.

Continuity mistake: When Goofy searches through the dresser drawers one of the ghosts causes trouble, then Goofy breaks through the top of the dresser and winds up trapped inside, but when all four ghosts appear the dresser top is perfectly fine and that damage has vanished. Also, two of the drawers (one large and one small) fall out of the dresser, but as the four ghosts are pushing the dresser those two drawers have reappeared in their proper places.Super Grover
