It's a spell that was banned after the dark times. It was used on humans who mocked us by dressing up like creatures. It was used on them to turn them unto the very creatures they were mocking.
~ Agatha "Aggie" Cromwell about the Creature Spell.

The Creature Spell is a frightful magic curse capable of transforming costumed humans into living monsters their guises resembles, and it is one of the 2 most dangerous spells in the 2001 Disney Channel Original Movie Halloweentown II: Kalabar's Revenge.

This forbidden enchantment was banned during the foundation of Halloweentown a thousand years ago after being used on the humans who first feared their former fellow magical/non-human inhabitants of Earth by mocking them with their costumes, pretending to be monsters, into the physical manifestations of monsters they pretend to be.


Kal, before successfully casted the Creature Spell upon nearly all of the Mortal World.

Centuries later, the young warlock Kal in preparations to fulfill his later late father's hateful ambition of humanity's destruction and his own quest for power, finally casts the incantaion and unleashes the Creature Spell on all costumed people at Riverview High School's Halloween party at midnight, transforming everyone (including the school's principal as a yellow Cyclops, Gwen Cromwell as a fiendish dark-green goblin, and Marnie Cromwell's high school friend Cindy as a vicious vampire) in a monster movie caricature of Halloweentown (just as the Gray Spell has transformed all of Halloweentown into a monochrome caricature of the Mortal World) in an effort to enspell and rule Earth this way.

Marnie Piper and Luke later used a Welsh time travel spell that the now discolored Aggie written down in order to evade Kal's spell with Marnie (having trouble) reading the incantation that reads "Pawb 'r Ddiwrnodau anad Heddiw, Archwn Adawaist ni Chofnoda". First time was 5 minutes when Aggie becomes cursed by the Gray Spell. Second time to Earth's primitive caveman times. The third time to a now empty version of Gort's house with Kal taking everyone there "offline" via a limbo spell he cast. The fourth and final time Marnie used the time travel spell and finds herself with Luke and Gort in the ogre's junk-filled abode 50 years prior. After Marnie accidently left the note with the written time travel spell on it somewhere on the lost items within the house, not realizing the grounds Gort's house was built on has the magical power to not only attract lost objects from anywhere in the universe like a magnet, but also to make things that ended up here to go "poof" as in forever erased from existence. While a troubled Marnie utters the time travel spell unsuccessfully which instead brings more things to Gort including a Victorian-styled curly hair on his hair and silly-looking top hat and garden gnome objects, Gort himself had enough of it and lets both Marnie and Luke to quickly get back into present-day Halloweentown via a mystic doorway called a Timeline.

Luke and Marnie returned to Gort's house to free Aggie from the Gray Spell, but they were all 15 minutes late to reach the portal to the Mortal World as Kal successfully initiates the Creature Spell by turning the costumed party guests including Gwen Piper and Marnie's school friend Cindy at Riverview High School's Halloween party into living and nightmarish, movie monster version of themselves.

After the good witch Marnie Piper defeated Kal and retrieved the 2 Biblio Magica copies, her grandmother Aggie Cromwell, undoing the Creature Spell by chanting the incantation backwards and outloud, she and Marnie, along with Luke, Dylan and Sophie, returned to Halloweentown. Together, they all begin inciting "Trapa" outloud everywhere in Halloweentown and freeing everyone including Benny Deadman, Astrid and Gort, from the Gray Spell. Aggie Cromwell then cast her magic with a wand into returning the brick block back to Halloweentown's fabled Jack O' Lantern monument.
