In the original theatrical cut, "Little Bitty Pretty One" plays during the scene where the monsters attempt to scare a baby. For some reason, this is replaced with a different tune, yet not credited. The television airings, however, keep the original song intact.
In the DVD and theatrical cut, when Brian is first in the monster's world, he runs into a creature that has long legs and says, "Trick or treat, smell my feet." For some reason, in most television airings, this is changed "Anyone who is a friend of Maruice's is mine."
