Witches in Stitches (1997)

Hop aboard a broomstick for this tale of two dim-witted witches who accidentally turn their sister into a jack-o-lantern on Halloween...and that's just the beginning of the story. Join the silly sisters as they turn a typical suburban town topsy-turvy with their inept attempts to rescue their sister-turned-pumpkin on Halloween night. Watch them fly around town, go trick-or-treating for the first time, and pop in on a children's Halloween party.
