Blastoise: Heavy armoured terrapin/tortoise, with the face of a Snapping Turtle. The jets are based on the Mollusc Siphon(cephalopods mostly), and the muscle tissue can extend, harden and rotate so water pressure and accuracy is increased (in before dick joke). The thing is, these siphons are very vulnerable compared to the rest of Blastoise's armour, so many trainers incorporate metals plates for protection.
Keep up the cool work!
Very beautiful <3
