Questionable Creatures from the Deep

A shapeshifting monster that seduces humans while disguised as a human. This isn’t to keep their secret; it’s just because they are repulsed by monsterfuckers.

Feathered mustelids

An empty blue whale that lives at the surface of the ocean. There’s nothing in the veins, nothing in the stomach or other organs, nothing in the skull, and every space is connected to the others by empty fleshy tubs just big enough to crawl through. It swallows smaller animals, and all animals are smaller, even humans on some boats. They get trapped in its organs, and after it is filled with enough creatures, the entire whale shrinks rapidly to the about the size of a seal, crushing everything inside to an easily digestible slurry.

Carnivorous giraffes who have flexible necks and who can stretch their jaws all the way down to their chests. It blends in perfectly with zoo or sanctuary giraffes, where it eats birds and squirrels and almost never takes children when the parents aren’t looking.

A peacock but all the feather eyes are actual eyes that cause hallucinations and aggression in anyone who looks at them. It wanders through crowded areas and then feeds on the remains after everything calms down.

reverse bermuda triangle where boats and planes periodically rise out of the water. the vehicles are not of a known make, and as for the people, they are genetically human, but as of yet unidentified.

Cherries that tie your tongue into a knot

A dog that sheds its skin like a snake instead of shedding like a dog

A mosasaur, but with a whip tail like a thresher shark.

A dragon, but with the regenerative abilities of an axolotl

Megafaunal flatworm

An immortal shapeshifter that feeds on guilt. It hunts by causing horrific accidents that mangle or kill it while in the shape of children or sweet animals, and feeding on the person who thinks they are responsible.

A werewolf that hates furries. It does not see the irony

Shrikes the size of the eagles from Lord of the Rings. They cannot be killed.

A centaur, split through time. He very rapidly switches between Horse and Man. This transformation is instantaneous. He has no control over it.

Kraken but with sock puppets for tentacles

A kangaroo the size of a Utahraptor.
