To grab one, just order the new Berry Battie Daydream Refresher at participating locations while supplies last.

Halloween has officially taken over Dunkin ', and the chain has another surprise brewing for its Refresher fans.

The spooky season already brought plenty of colorful drinks to the menu, but Dunkin' wasn't finished having fun with its holiday lineup.

Now, there’s a new reason to keep an eye on their Refreshers this month: Dunkin’ is giving away a free bat-themed koozie when you buy their newest drink, but the deal is only good for one day.

The drink starts with Dunkin’s Berry Clementine base, giving it a sweeter, creamier makeover with blueberry flavor and oat milk.

It’s topped with bright purple Marshmallow Cold Foam and a pair of edible candy eyes for a full Halloween look.

Designed to fit around the cup, the koozie features purple bat wings that stick out from the sides, essentially giving your drink its very own costume.

The bat koozie arrives right in the middle of a packed seasonal rollout at Dunkin', which first started hitting stores on Sept.
