I watched an interview of Jorb and Totalbiscuit and found cyrptids would be in the game. This is pretty much a list of suggestions of mobs and maybe a few skills. However, due to some problems with the client, I can't be on so please allow some leniency if I accidentally add something on this list.

Cyrptids
Bigfoot
-A classic, what can I say? It is basically a hairy large human-like creature that hides in woods while leaving behind huge footprints.
Abominable Snowman(YETI)
-Pretty much a variation of Bigfoot except it lives in the snow
Mongolian Death Worm
-A worm that is said to live in sandy areas. It is said to be able to shock its prey to submission similarly to an electric eel but could also spit acid that can corrode away metal.
Wolpertinger
-it is pretty much a rabbit with wings and antlers
Man-eating tree
-There are many legends about this tree. There are also many variations of this tree. Some of the legends say that it releases a sort of sleeping drug then attacks the sleeping prey. Others say that it wraps slowly around its prey using vibration.
Unique Cyrptids
For these, perhaps they spawn rarely,but when they do, they don't despawn until killed. When they spawn, a message appears on everyone's screen saying a quote to help identify what cryptid spawned.
Beast of Gevaudan
-Basically this is some wolf like creature that harassed the France countryside. Several witnesses claim that it would recieve brutal blows, but would not die. Apparently the French government supplied a large amount of money and manpower to hunt it down. This beast alone has commited aproximately 210 attack, 113 deaths and 49 injuries, and 96 victims whom were partially eaten.
You feel your hairs rise as you hear a thundering roar. Hopefully its source would be far away...
Beast of Dean
-A beast that is said to live in england. It resembles a wild boar, but is abnormally olarge. It is reputedly strong enough to fell trees.
You hear the sounds of a wild boar, but something isn't right about it...
Black Shuck
-A ghostly black dog that roamed the countryside. It is recorded as an omen of death with flaming eyes that are either red or green. This specter has been recorded headless or even floating on a carpet of mists.
You feel an uncanny wind that smells faintly of fur and sulfur.
Kraken
... do I really need to explain what a kraken is?
If you are near waterYou see schools of fish fleeing from some unknown predator
if you are not near waterHeavy winds are blowing from the sea, caring a stench of carion...

An entity said to wear a helmet, oilskin garments, and "devil-like" aspects. The humanoid is siad to breath blue and white fire, have sharp metalic claws, and even said to speak English.
