Other mistake: At the end of the show when the misfit toys are being delivered, the elf in Santa's sleigh gives an umbrella to each of the misfits so they can glide down with the exception of the bird, who jumps off, apparently forgetting that he is a misfit toy and can't fly; as he stated earlier in the show, he can only swim.
Other mistake: When the Big Bad Wolf is demonstrating to Bugs how to ring the bell properly (so the trap works), his hand lands on the side of the bell instead of the top, yet the trap still works and the bell still dings.
Continuity mistake: When we see a close-up of the meter, there is a box saying "10 Centavos for One Hour." The words were not in the box in the previous shot.
Continuity mistake: When Daffy is clawed by the bear, he loses his hat in the process. But when we Daffy running in the next shot, the hat is back on his head again.
