Ever heard of Hermit Crabs? They have a soft abdomen.

Also, i t ' s a n e x o s k e l t o n for christ's sake. See what the legs are attached to? Also, cephalopods don't have jointed exoskeletal limbs, but an arthropod could indeed, have tendrils. It is a simple appendage that is not that quite difficult to evolve. Case closed...
