The Bleaken is an imaginary spirit who is described by Teddy as the anti-Santa. In "The Bleakening", the kids believe that the creature has stolen their presents and Linda's improvised mini Christmas tree with her treasured ornaments and hunt for it.
He steals naughty children's presents and takes them back to his lair. Teddy tells the kids that The Bleaken feeds off sadness and anger.
He is described by Teddy as a horned creature with lizard skin and black feathers. His horns appear to resemble those of a reindeer.
- The Bleaken is a parody of Krampus; a Christmas demon of European origin that punishes children that have misbehaved.
