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: In the ceiling tea party, Mary Poppins offers Bert some sugar, and when he responds that he would not like any, his Cockney accent is gone.
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.
Other mistake: When Eliza throws the slippers at Higgins, one bounces off him and falls in the area of the doorway and the other lands in the middle of the hall. One slipper is seen in the hall in two different scenes, then when Higgins goes to pick them up they are both together in the hall.
