Continuity mistake: When Casper strikes the picture of Daffy Duck on the stone, the impact makes Casper dizzy and he drops his club in the process. But when Casper walks past the stone to hunt the duck that Daffy promised him, there is now no sign of the club.
Continuity mistake: When Daffy gives Casper a card, he is seen holding the card with his fingers in the middle, but when we see a close-up of the card in the next shot, Casper's fingers are now at the top of it.
Continuity mistake: When Casper the Caveman takes off his caveman's outfit to go swimming, he puts his outfit near the edge of the bank. After Daffy says that he can't swim, he reverses back onto the land and goes and collects his suit, but this time the suit is now much further away from the bank.
