[Lo-W4] Sneake

The word "sneake" is pronounced like "sneak + the sound of surprised pikachu face (alternatively, the E at the end of "appearance" or "use" sounds kinda close)" xD
It's a combination of "sea" + "snake" and that it didn't turn into a "seake" is because I made a typo when I wrote the name lmao

Appearance:

Sneakes are very long and giant creatures. They come exclusively in dark and dull colors.
They have the head of a fish, but the body of a snake and the end of their body ends in the rattle thing of a rattle snake. They have one big fin that starts at the head and ends after about a third of the body. It usually has 2 tips and one much, much larger tip that is roughly as long as a third of the body.

Habitat:

Sneakes only live in fresh water and in warmer regions. They might live within the Crystal Empire, but they would freeze to death once they were outside of it. The Grifix settlements in and around the Everfree Forest are easily warm enough for them to survive.
As they are large, they only live in deep rivers or deep ponds or lakes. They are also too heavy to swim and as such, remain on the ground of those.

Diet:

These creatures are strictly herbivores, eating only the few plants that grow at the ground. They are also able to consume rocks, but they only do so if they have to. Eating rocks takes a lot of energy out of them as they have to convert the rock material into nutrition first.

Means of Transportation:

Having the body of a snake, Sneakes also slither over the ground of the lake. They are swift and quiet and can be surprisingly fast. Most of the time, they like to majestically slither over the ground though.
Sometimes, they will also jump up in the water and slither through the water, but as they are too heavy, they will slowly descend back to the ground. No Sneake has ever managed to hit the surface.

Miscellania:

It is currently unknown whether Sneakes actually have a predator, but they prefer to stay on their own and use the rattle of their tail to keep others away from them. Most are already intimidated by their size anyways lol
If they are still threatened by something (or someone), they will wrap their body around the intruder and squeeze them; not quite killing them, but definitely giving that something a scare of their life.

Grifix Use:

Honestly... I'm not sure how much Grifix are actually making use of them, considering that they live at the ground of deep lakes, are rather large and not innocent.
The rattle at the tip of the tail makes a great toy for young Grifix cubs, but as it's not easy getting one, it's a rather rare and highly valued item amongst the Grifix.
It is said though that the Sneake's meat tastes delicious.

Legends and Rumors:

It is said that somewhere in Equestria, there's a Sneake living that's much, much larger than anything you have ever seen. Not even Enchanted's hair can dare compete to it.
This might just be something made up by the Selenara's maids, but there are ponies speaking of such a great creature somewhere out there...
