[Martial Arts] Are mollusks susceptible to Arm Lock and Leg Lock?

Extra Arm (Extra-Flexible) adds one extra arm that's flexible, but does nothing to the two existing arms. If that enhancement is allowed on Extra Legs, that would make the two extra legs flexible, but would do nothing to the two existing legs.

A technicality. As per B55, the cost of a modification to your existing two legs is worth 0.1 * the percentage increase/decrease of the enhancement/limitation.

Porting over Extra-Flexible (50%) would cost 5 points per leg. This seems a bit steep, since it is of far less use to legs. This is based on the increase in the cost of an extra arm (50% of 10 points).

We can apply this to legs, as well, I do believe. Examining the cost of Extra Legs in different levels, it appears that two additional legs is roughly worth 5 points (or 2.5 points per leg). Now 50% of 2.5 points is 1.25. You can then multiply this by the number of legs you have (4) and get a cost of 5 points for all them to be tentacles. That seems reasonable to me.

Put the Flexible enhancement on the two original arms.
Buy six Extra Arms with the Flexible Enhancement.
Take the feature No Legs (Slithers) 0.

That would make something that moves around like an octopus on the sea floor.

Normally the down side of the No Legs (Replacement) features is that a random hit to the legs now hits the torso. Your DM might accept random leg hits now hit a random arm.

That's not a down side at all; it's actually the upside. The downside is that you are incapable of kicking. Judging by what Gurps Fan has said so far, I'm guessing he wants to still be able to smack things with his feet-tentacles (feetacles?).

Sorry for the pedantry but you probably want to narrow your terminology. You really only seem interested in pseudo-cephaolpods and cephalopods are only one sub-set of mollusks.

The great bulk of mollusks belong to the gastropod groups (snails and slugs) with many other members of the bivalve group (clams and so forth).

So most mollusks _are_ immune to Arm Lock and Leg Lock due to a lack of arms and legs. This is the point which confused me when I saw you're title. :)

I think I see your point. However, after a close examination of p. B55, I found an interesting sentence: "You can apply the following modifiers to all your legs", just above the Special Enhancements section. It suggests that enhancements on Extra Legs work on an all-or-nothing basis, not a per-leg basis. Therefore,

• Two-legged creature whose two legs are flexible: 5 points (= 1/10 of the percentile value of Extra-Flexible).
• Three- or four-legged creature whose three or four legs are flexible: 8 points (= Extra Legs [5] plus +50%, rounds up).
• Five- or six-legged creature whose five or six legs are flexible: 15 points (= Extra Legs [10] plus +50%).
• Seven- or more-legged creature whose all legs are flexible: 23 points (= Extra Legs [15] plus +50%, rounds up).

Oh, sorry, English is difficult for me.

That's alright. This is more Marine Biology than English anyway. Very specialized vocabulary.

The point value of Legless is -30; I seem to recall from Transhuman Space: Changing Times that No Legs (Portable), which gives you no means of moving yourself around but lets someone else carry you, is about the same. That suggests that the point cost of the first two legs is 30. A 50% enhancement would cost 15 added points. So going from human normal to having two tentacular legs would be 15 points.

That's inconsistent with Basic Set. That calculation would conclude that having two legs that can't kick would be worth -15 points (Cannot Kick, -50% of 30 points), but actually it's -5 points. See p. B55.
