*POSSIBLE SPOILERS* New titan designs revealed?

This is very doubtful, so take this with a grain of salt, as I did.

This person over at Toho kingdom has apparently seen the finished cut of Godzilla king of the monsters, and made some drawings of the titans.

First we have drawings of the Mountain titan! According to the person over at Toho kingdom, the titan has a mountain on his back, and is some sort of cow-like titan.

Next we have the Mammoth titan. It looks very ape-like, and according to the guy at Toho kingdom, is a cross between Kong and a Mammoth.

Finally, the Spider titan! It seems to have tentacles near it's mouth, and is described by the person over at toho kingdom as looking a bit like cthulhu. 

What do you guys think? Is it legit? I don't know for sure.
