New sea monsters

Cthulhu... It's not Lovecraft, stop with that, seriously... Cthulhu has nothing to do in Sea of Thieves !

@billatz The geek in me requires that I correct this; Cthulhu is not a monster like say, a kraken, or a megalodon.
Cthulhu is a character, and as such is usually portrayed with unique characteristics within a specific genre.

And, like @Grievous32 said, he doesn't quite belong in Sea of Thieves.

Plus, we already have a kraken, how many more tentacles can we handle?

I'm fine with leviathan, it could be the sea serpent, but lovecraft creatures don't really belong in SoT.

To be fair, there are indications that Cthulhu is actually inspired by the Kraken, as the stories bear a very strong resemblance to Alfred Lord Tennyson's poem, "The Kraken".

Below the thunders of the upper deep,
Far, far beneath in the abysmal sea,
His ancient, dreamless, uninvaded sleep
The Kraken sleepeth: faintest sunlights flee
About his shadowy sides; above him swell
Huge sponges of millennial growth and height;
And far away into the sickly light,
From many a wondrous grot and secret cell
Unnumbered and enormous polypi
Winnow with giant arms the slumbering green.
There hath he lain for ages, and will lie
Battening upon huge sea worms in his sleep,
Until the latter fire shall heat the deep;
Then once by man and angels to be seen,
In roaring he shall rise and on the surface die.
