Statting a humanoid gestalt made of alien jellyfish

[Seneschal]

A GM of mine plans on running a far-future silly space-opera, so we're on the lookout for interesting SF characters. Yesterday, on the CGHUB Mass Effect 3D Challenge (the only rules were to design something that fit the Mass Effect setting, even if it's a new alien species), I saw a particularly interesting submission: a colony of polyp-like creatures that come together and mimic a humanoid (and even change colour/texture).

So, how would you guys stat such a thing? At first I thought Morph (Universal, +50%; No Memorization Required, +50%; Cosmetic Only, -50%) [150] would do it, but that's an insane amount of points for a largely superficial change. Assuming the polyps cannot impersonate anyone, and can only fool someone in poor lighting (e.g. they get mistaken for a human in an alleyway, but speak to them face-to-face and you'll see through it - like the Judas Breed bug from "Mimic"), that would be more like Elastic Skin. Except that they probably can imitate inanimate objects (again, badly), which is outside of the reach of Elastic Skin.

Other possible traits:

Compartmentalized Mind [??]
Doesn't Breathe (Oxygen Absorption, -25%) [15]
Double-Jointed [15]
Injury Tolerance (Homogenous) [40]
Injury Tolerance (Detachable Body Parts) (Detachable Head, +15%; Instant Reattachment, +50%; Reattachment Only, -50%) [40]
Injury Tolerance (No Blood, No Neck) [10]
Pressure Support 2 [10]
Scanning Sense (Field Sense) (Extended Arc, 360°, +125%) [22]
Slippery 5 [10]
Vibration Sense (Universal, +50%) [15]...

This all assumes it's a marine organism. They probably don't have eyes, so Blindness [-50] would help alleviate the huge cost of Morph and IT. Dependency (Water, Common; Weekly) [-10] might also be appropriate.

Any other ideas?
