Name: Frank Gender: Male Race: Human Age: possibly in his late 20s or 30s Occupation: Child kidnapper Appearance: Very tall, short black hair, black eyes with white pupils. He wears a blue sweater with white strips and black pants with matching black shoes Personality: In spite of Frank's lifestyle and choice of job, he seems to be a relatively decent guy. Oftentimes he turns on the edge of villainy, but never seems to personally enjoy bringing misery together others, nor does he have any greater affiliation with the cult like other adults in the town. In a way, this could make him into an anti-villain, being a character who does villainous acts, yet isn't a vile or rude person in their own right.

Relationship: He also has an off-and-on relationship with Kevin, especially with their differences and interactions with each other. Frank kidnapping children from the store and Kevin chasing after him, yelling. They are mostly considered as "ex's" yet they both share a soft side for the kids, Skid and Pump whenever they interact with them.

Skid is one of the two main protagonists, alongside Pump. He's an 8-year-old boy who is almost always dressed in his skeleton Halloween costume. His costume consists of a black outfit with white skeletal markings and a skull-like mask. Underneath the mask, he has dark hair and buck teeth. Personality-wise, Skid is extremely energetic, cheerful, innocent, and naïve. He absolutely loves Halloween and treats practically everything as an opportunity to celebrate "Spooky Month." He can be surprisingly trusting of strange people and creatures, although he sometimes realizes when something is suspicious. His innocence can also get him and Pump into dangerous situations because he doesn't always understand how serious something is. His closest relationship is with Pump, his best friend. The two are almost inseparable and spend most of their time getting into bizarre adventures together. Skid also has a very loving relationship with his mother, Lila.

Pump is Skid's 7-year-old best friend and the other main protagonist. He wears an orange pumpkin mask with a green stem and a mostly black outfit resembling a little suit. Under his mask, he has curly brown hair, white skin, and a missing tooth. He's shorter and somewhat rounder than Skid. Pump shares Skid's enthusiasm for Halloween, but he can sometimes seem a little more aware of how strange or frightening a situation is. He's still a mischievous kid who happily follows Skid into whatever bizarre situation they've discovered. Pump and Skid have an incredibly strong friendship. They're constantly together, celebrate Halloween together, and repeatedly find themselves involved with supernatural creatures, criminals, and other strange people. Pump is also connected to the Wonder family, including his older sister Susie.
