"Hideous Halloween" is a Halloween episode of Pearlie.
Halloween is a scary time for fairies and elves. Pearlie, Jasper and Opal hide out in a magical pumpkin conjured up by Great Aunt Garnet and tell scary stories to pass the time til dawn. Saphira refuses to join but when Ludwig gets locked outside, his efforts to get into the spa give her the biggest scare of all. Jasper longs to be just a little bigger, but when he messes with some fairy magic he gets more than he bargained for and ends up person-sized! Pearlie must keep him hidden from persons until they can locate the Turquoise Fairy to undo the spell.
