Continuity mistake: During the Deathball Match, the booth window is smashed and Wernstrom gets knocked onto the court, however in the next overview shot, the window is intact and he is still standing behind it. (00:15:10)
Other mistake: When Fry and Colleen are lying in bed, his hand is around her shoulder but it is the same colour of Colleen's skin. (00:04:25)
Revealing mistake: When Leela brings soup to Zap and Amy in bed. Leela is wrapped up by a tentacle. The animator forgot to erase the lines of the tentacle as it overlaps. A huge graphical error can be seen.
Continuity mistake: In the suicide booth, the floor drops from under Bender. After it does, and Bender starts to drop, his arms are crossed, and his head is just above the level of the floor. A second later, he's back up, dropping, and his arms are flailing about.
Audio problem: When Leela says "I'm saving my neck for a rich handsome Dracula!" whilst being ambushed by Vivo, her mouth doesn't match what she's saying at the end of the sentence. (01:01:10)
