Pathfinder 1E Ooze vs Crippling Strike

[Stalker0]

So the notes for ooze says that they do not take extra damage from sneak attack. But it does not technically say they are immune to sneak attack.

So the question is, would sneak attack riders (like the crippling strike that works when you get a sneak attack) still work against an ooze?

I think the relevant text is in Crippling Strike:

An opponent damaged by one of her sneak attacks also takes 2 points of Strength damage.

Since an ooze cannot take additional damage from precision-based attacks, I would say that Crippling Strike is negated. If I were to picture it in my mind, crippling strike lets you hit an important muscle or tendon. But an ooze is just ... ooze. There's nothing to damage.
