This creature is a massive beast, such that only the deepest waters can fully contain it. For it’s gigantic size, however, it gracefully flows through the water, nary making a sound. Its central mass has eight huge tentacles, and beneath its girth lies a massive red eye, and a beak strong enough to easily crack through adamantine. The rubbery gray flesh of the huge cephalopod shimmers a dark blue, similar to the dark ocean around it.
Improved Grab (Ex): When Slaakelrupt hits an opponent up to Huge size with an arm or tentacle attack, it can constrict them.
Constrict (Ex): Slaakelrupt deals automatic damage with an arm or tentacle with a successful Grapple check against Huge or smaller creatures.

Ink Cloud (Ex): Slaakelrupt can emit a cloud of jet-black ink 80 feet high by 80 feet wide by 120 feet long once per minute as a free action. The cloud provides total concealment, which Slaakelrupt normally uses to escape a situation. Creatures within the cloud suffer the effects of total darkness.
