(first transformation scene i've done in a while)

Toothless bowed and arched his back, as he arched it, his spines started to retract into his back with a slight bone cracking sound, his spines retracted into him so were his wings, hip fins, and tailfin. Toothless’ legs started to shorten as they too retracted into his body, his underbelly began to turn grey as does his nose and the sides of his head, and the grey ran down to the end of his tail, the smaller nubs on the back of his head retracted as his ears sprayed out words as a membrane began to form between his ears and his neck, the membrane thickened to match the thickness of his ears which too started to turn grey and lengthen and form a point, which began to become part of the membrane and got wider near the middle of his neck before narrowing as it went down to where his shoulders were, belly plates started to form, his body began to lengthen, as it did his body started to become a bit cylindrical, blue diamonds started to form, forming a pattern that ran from before the membrane to down near the tip of his tail. The membrane began to form something like a hood, the underside of the hood turned red with white rings in the center, triangular scales formed on what were his ears, which went down to around the middle of the rim of the hood. His mouth was jarred open as his head began to change, his eyes changed position to face more forward, with horns forming above them, his pupils became slits, his tongue hung out as it too began to change, it began to lengthen and started to thin, the tips of his already forked tongue became more of a sharp point. His teeth retracted permanently except for 8, 6 on his upper jaw with the front 2 being retractable, and the 2 front ones on his lower, his teeth lengthened a bit making them more like hooks. He laid his head on the ground for a moment, his tail coiled up, he opened his slitted eyes, and he lifted his head shaking it with a slight annoyed hiss as his tongue flicked out, he blinked a few times, he looked down to try and rub his head with his front paw, but to his horror he no longer had them, he then slithered around franticly getting a better look at himself, he had fully become a snake but not just a snake but a cobra, and he was a big one too as his size didn’t change to make him the same size as a normal cobra.
