This is the larval stage of the dreaded Star Kraken
Star krakens are soft-bodied, multi-limbed molluscs, the family that includes octopuses, squids, cuttlefish, and nautiloids. It is likely they are some unimaginably huge version of octopuses. Like other cephalopods, they are bilaterally symmetric with two eyes and a beak, and their mouths at the center point of their radial tentacles. Their soft bodies can rapidly alter their shape, enabling them to squeeze through surprisingly small gaps -- if you can call anything on this scale "small". They trail their appendages behind them as they navigate the Airts. They have a siphon-like orifice that is used both for for locomotion, as they harness the Airts to propel them through space, and draw in the gasses they need to breathe. It is possible that they may require less air to breathe than terrestrial organisms, or that they can respirate gasses that most terrestrial species find toxic. Star krakens are almost certainly invertebrates, like other cephalopods. While it is only a presumption that star kraken physiology works the same way -- due to their size and rarity, no one has been able to dissect one -- it is a reasonable presumption. Most of an octopus' brain is, as one would expect, contained within its head in a cartilaginous "skull," but its neural tissue also extends into its tentacles, which means that they move and operate with some degree of autonomy -- and it would seem observationally that the star kraken shares this unique advantage. The bulk of their major organs are located in their mantle, which is the capelike flesh between their head and tentacles. Star krakens are immune to the effects of decompression, and they are also effectively immune to the damaging effects of cold, fire, and radiation.
Ink Cloud (Ex) A larval star kraken can emit a 15-foot-radius cloud of ink once per minute as a free action while in space. This cloud provides total concealment. The ink persists for 1 minute. Jet (Ex) A larval star kraken can jet in a straight line as a full-round action. It does not provoke attacks of opportunity while jetting.
