I also prepared one creature for Valguero, although I am a very bad artist, but please rate the idea itself. I think thanks to this creature, people will be able to spend more time under water, and finally someone will remember about Dunkleosteus. This will make the game easier for some solo players and will also give the opportunity to "live" in the ocean not only at the late stage of the game with tech cubes, but also at the beginning.
Actually, this is the main idea - an underwater dwelling. By design, when Megasteria burrows (like a reaper), its central “tentacle” remains on the surface, like a wild basilisk, and enemies can see it. After this, in the list of actions you can select “go inside” and get into the space where you can build house 2/2/1. Essentially, this space will be under the texture, and it can be depicted as the insides of a starfish or like the hole in the ground and the ceiling from Megasteria. Of course, when Megasteria is dug up, the dwelling is destroyed, and all objects and animals are moved outside.
