What if they don't get squished by hitting blunt objects?

They only get crushed by sharp or fast projectiles or by being slashed, which means they can't be used defensively against those things.

They don't get squished when punching blunt objects since they're directly connected to the host.

Let's go with that.

EDIT: Just read your last post. They can stay inside his hand like that too, if ya want.
