Lupin and Jigen go from having separate beds to sharing a bed in between shots.
When Jigen tries to warn Lupin that the Loch Ness Monster has emerged, his neck becomes the color of his shirt for a few frames.
During Zenigata's fantasy, the background behind Lupin moves from left to right when it should be moving from right to left.
When they see the metallic Nessie has Fujiko, Lupin and Jigen shoot at it without thinking that the bullets might hit her.
