The Bogeyman

The Bogeyman is a frightening monster invoked by parents world wide to frighten their misbehaving children. He is usually depicted as a beast or ogre of some kind, although the visage of a psychotic old man is also not uncommon. One feature found in the legends of many countries is the large sack he carries, which to kidnap naughty children and take them away.

El Cuco

El Cuco is a ghost-like bogeyman type figure from the folklore of Spain, Portugal, as well as various Latin American countries. He is depicted in multiple different, usually horrifying ways, the most common being a huge troll-like man, covered in hair, with a Jack O'Lantern as a head and carrying a huge sack in which to abduct children.

Parents often warn their children that if they don't behave, El Cuco will come and get them.

Spluggling

Splugglings are a form of lichen that posses rudimentary organs and other structures commonly associated with animals. They breed by "budding" off smaller Splugglings, who are genetically identical to their parents. They usually feed on rotting matter found in swamps or bogs, like leaves, logs, or animal carcasses.

Sabascatcth

The Sabascatcth is a lonely four armed brute which haunts forests looking for stray children. If he should happen to catch one, he'll keep it around as a companion for a little while, until his hunger overwhelms his desire for companionship. They are extremely stupid, and have been known to fall for the simplest tricks.
