Wendy's is bringing Boo back! Bags of Halloween toys for adults

Wendy's is offering lots of family fun this Halloween.

The chain offers its Boo! Bag meals for adults and Frosty Frights meals for kids this spooky season starting Monday, October 21st through November 3rd, 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, as well as a glow-in-the-dark Bone Chiller Frosty figure and a boo! Book for Frosty vouchers.

The Wendy's Frosty Frights children's menu includes the choice of four-piece chicken nuggets, a hamburger or cheeseburger, with Jr. Hot & Crispy Fries or apple bites and a children's drink.

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

The chain also brings back its boo! Books that can be purchased individually in the app in the Give Something Back category or through self-order kiosks in stores.

Buuuuh! Books are sold for $1 and include five vouchers for a free Frosty and one children's meal voucher for $1.99. $1 from every Boo! Book sold, 90 cents go to the Dave Thomas Foundation for Adoption, which helps find permanent families for children in foster care.

The boo! Books can also be ordered in bulk for those who want to give something other than candy this Halloween. The vouchers are valid until December 31, 2024.

Wendy's isn't the only restaurant celebrating Halloween with a spooky food offering. McDonald's brought back its Boo Buckets this October, available in four different designs.

Dunkin' Donuts also has its own trick-or-treating bucket called the Dunkin Munchkins Bucket, as well as a DunKings Halloween costume.
