Creature Concept: Sealug

The creature name is Sealug (pronounced as Sea-lug).
It is a Massive-Giant Leviathan (Around 200 meters). It lives inside its giant nest, located very deep and far from most of the other living creatures. It’s a very tricky predator. It’s skin is full of rotten flesh due to acid. It’s color is mainly a dark shade of red and black.

Nest: It is a giantic nest, 2500+ meters long. It is full of intoxication gas (description on the intoxcation gas in the next paragraph). The nest is full of dead leviathan bones, rotten flesh and many other substances. Inside the nest, you can spot leviathans which are still maturing (size around 40 meters - 150 meters). If you approach them, then they will release intoxicative gasses but won’t be as strong as the fully-matured one.

When you go near its nest, at least 1 of them is roaming around the nest to hunt. If you try to approach even one of them, they’ll release intoxicative gas inside the water. The gas will make you hallucinate, and many identical Sealugs will spawn (due to hallucination) and they’ll rush towards you, after attacking you with their rush attack they’ll disappear and blind you for 20 seconds. When blinded, the real Sealug will constantly try to attack you.

Extras (optional):

• During the starting parts of the game, you may hear a few sounds of Sealug.. like its groaning, moaning or heavily breathing.
• When inside the nest, the young Sealugs will scream at an extremely high-pitch sound as a “cry for help” to the matured ones. It’ll take approximately 3 minutes for the matured ones to arrive (the nest is extremely big, so it takes the matured ones time to arrive).
