Wendy’s is having lots of family fun this Halloween.

The chain offers their Boo! Bag meals for adults and Frosty Frights meals for kids this spooky season, starting Monday, October 21 through November 3, while supplies last.

Adult customers, or “kidults” as Wendy’s calls them, can order the limited-edition meal, which includes a Dave’s Single, a small Hot & Crispy Fry and a small chocolate Frosty, along with a glow-in-the-Dark Bone Chiller Frosty figure and a Boo! Book for Frosty coupons.

The Wendy’s Frosty Frights kids meal includes a choice of a four-piece chicken nuggets, a hamburger or cheeseburger, with Jr. Hot & Crispy Fries or apple snacks and a children’s drink.

Collectible figures will also be part of the Frosty Frights kids’ meals. There are 11 different figurines such as Franken Frosty, Frosty Bite, Coolie Ghoulie, Brrr Beast, Cold Spell and Junior. Prices for both meal deals vary by location, a Wendy’s spokesperson tells PEOPLE.

The chain also brings their Boo! Books that can be purchased individually in the app in the ‘Give Something Back’ category or via self-order kiosks in stores.

Boo! Books sell for $1 and include five coupons for a free Frosty and one coupon for a kids’ meal for $1.99. Of every $1 Boo! Book sold, 90 cents goes to the Dave Thomas Foundation for Adoption, which helps find forever families for children in foster care.

The Boo! Books can also be ordered in bulk – for anyone who wants to give out a treat other than candy on Halloween. The discount coupons are valid until December 31, 2024.

Wendy’s isn’t the only restaurant celebrating Halloween with a spooky meal deal. McDonald’s brought back their Boo Buckets in October, which come in four different designs.

Dunkin’ Donuts also has their own trick-or-treat vessel called the Dunkin Munchkins Bucket, along with a DunKings Halloween costume.
