After the violent shaking like an earthquake, a moist humidity suddenly swept in like a transparent palm slapping their faces. The palm was drenched in water vapour, even causing the moisture in their skins to turn saturated.

Simultaneously, an enormous deep blue tentacle brushed in through the arched door, its one metre huge suckers tightly pasted against the mountain wall.

When the tentacle gripped tighter, cracks immediately formed on the steel-like mountain walls. Then another two enormous tentacles flushed in, one of the tentacle surface hosted a terrifying cauterized wound, striking bare red over the injured area looking like a prawn that was cooked.

Following that, the humongous ocean blue octopus borrowed the strength of its 3 tentacles to pull back into the mountain belly. Indeed, it was that legendary creature - Ocean-freak of Moria!
