Happy Halloween, millennial nightmare fuel. Nickelodeon and Victorious alum Elizabeth Gillies just won celebrity Halloween 2026, transforming herself into Luke — the goblin sidekick from Disney Channel’s 1998 classic Halloweentown — with a jaw-dropping full-prosthetic makeover.

The 33-year-old revealed the costume on Instagram, where she is barely recognizable under a bulbous prosthetic nose, facial boils, elf ears, and a red crushed velvet cape. “I’m something of a big cheese around here,” Gillies captioned the post, quoting Luke’s most iconic line — as Page Six reported on Oct. 30.

In the movie, Luke (played by Philip Van Dyke) starts off as villain Kalabar’s spy before ultimately helping Marnie save Halloweentown — and the 1998 DCOM has only gotten more beloved with time. Gillies’ tribute is hitting millennial Disney Channel fans right in the nostalgia: Page Six reports followers flooded the comments with “No one has ever been this iconic,” “This is unbelievable,” and “THIS IS THE BEST COSTUME EVER.”

The timing couldn’t be better: ToledoBuzz recently reported that Disney is developing Halloweentown 5, 20 years after the last installment.
