If you’re like most people who love Halloween, you’re already trying to decide what costume you’ll wear for the holiday this year. Whether you’re heading out to a party with friends or to the Oogie Boogie Bash at Disneyland Resort, the perfect costume can make all the difference. And what’s better than the perfect costume? Why, the perfect accessory, of course! This new Zero on a leash is the perfect accessory for any costume.Â

If you’re familiar with “Nightmare Before Christmas,” you’d know that Zero is the faithful best friend of Jack Skellington, the Pumpkin King who’s bored with the everyday humdrum celebrations surrounding Halloween. He stumbles upon Christmastown and just has to know what it’s all about. Once he learns a bit more about the new town, he devises a plan to kidnap Santa Claus and take over Christmastown, but soon, Jack himself has a major change of heart.

But Zero is Jack’s ghostly sidekick–the “Max” to Jack’s “Grinch,” if you will. So we can see why Disney fans would choose this accessory for their costumes; after all, you don’t get much more loyal than Zero.

This Light-Up Zero on Leash toy is now available for $30 at select merchandise locations throughout Disneyland and Walt Disney World. (Specifically, we found this one at New Orleans Square and World of Disney.) You can even pair it with a costume inspired by Tim Burton’s “The Nightmare Before Christmas.” Add Zero to your Halloween ensemble this year, and you’ll never go to a party alone. Zero comes with his very own leash, and since he’s a ghost, he doesn’t require too much maintenance.
