TWIX, the bar of two, announced plans to celebrate Hallowmas — where ghouls meet garland and cobwebs meet carols to enjoy the best of Halloween and Christmas. Through this celebration, TWIX is making sure fans don’t have to choose between extending “Halloweekend” celebrations or decking the halls.

Introducing the TWIX Hallowmas Grotto — a two-night-only, pop-up in New York City that transforms holiday spirit into a whole new kind of haunting. Hosting the event is the face of Hallowmas – Zombie Claus – a jiggly, jaw-rattling Santa.

Guests are invited to step into an immersive world that’s bursting with spooky thrills and yuletide cheer, featuring:

• Interactive experiences and photo ops

• Zombie Claus’ favorite Hallowmas Treat Pack, featuring TWIX Ghoulish Green Fun Size and an early, taste of the new TWIX Snowman

Location: North 10th Street & Union Avenue, Brooklyn

Hours: 4-11pm, daily
