Under-used supernatural creatures

Thai Mythological Creature is underused even Thai Fantasy writer except me not even use They can be found in Himmapan.com http://www.himmapan.com/

When the mist rises from the lake around Tenochtitlan and rolls into the city, Tlacanexquimilli comes with it. The name means something like “human-appearance bundle” and it’s depicted as a sort of funereal body-bag in the Florentine Codex, but later in the colonial period some Spanish illustrator apparently depicted it as a kind of snarling monkey chicken body horror person for I don't know why, I found it by accident and it's barely mentioned on English-speaking parts of the internet.

Anyway. Tlacanexquimilli is an omen of disaster associated with the god Tezcatlipoca, and its cries in the mist sound like someone dying of sickness, but the best part is that when soldiers are sent to convince it to go away, it tries to give them increasing numbers of cactus spines. The soldiers keep dismissing its gifts as "useless", and eventually it leaves because its offer of friendship was rebuffed.

Tlacanexquimilli, nightmare spirit of "I found a cool leaf and I want you to have it".

Arabian ghouls/Ghuls?

The gulon is a creature from Scandinavian mythology that looks somewhat like a wolf, and is known for being quite the Big Eater. Look it up.

PLEASE let me tell you about the bake-kujira.

The carcass of a whale is an iceberg-sized mass of unprotected protein. In the wild, 'whalefalls' are a critical food supply that support entire ecosystems in the abyssal zone of the sea. If found beached or hauled ashore, they can be individually large enough to feed a whole fishing village. As such, whales are a prominent part of Japanese nautical folklore.

Bake-kujira is one of these. "Kujira" means whale. "Bake" is part of the names for a variety of yokai and is often translated 'ghostly', but in other contexts may mean 'changing', 'disguised', or as a suffix equivalent to '-ification'. In this case, 'liminal' seems like it might be appropriate (in my very amateur opinion).

The folktale (there is apparently only one) describes the bake-kujira as a skeletal whale carcass, found adrift at sea by whaling boats during a storm. As they got closer, they found that its remains were in some way still alive. The ocean around it teemed with schools of fish, and the sky with flocks of scavenging birds, but strange and unfamiliar ones that experienced anglers did not recognise. On the horizon was a phantom island that shouldn't have been there. Eventually, the whale and its companions vanished back into the sea, never to be seen again, leaving only the speculation that it might be the ghost of a vengeful whale or some strange god of the deep.

In my mind it's half Moby-Dick and half The Mist, but for something that sounds like a like a very modern kind of horror it is older than both and I am obsessed.
