Good point I sure that the sand probably hardened on its body making it a lot tougher, I think the reason why the Dobo Sub's tail had so much knock back was probably because the bones sticking out of its tail are more aligned now allowing it to work like a paddle/fan so I'm guessing it prove to be more of a challenge then normal Dobo.
