Echidna appearance and reinforcement 1

Noelle was perched on the ruined bed. Her fingers were clutching a sweatshirt, with no shirt beneath. Still the Noelle he'd always known.

From the waist up.

Around where her pelvis should have been, she'd changed. The mass of tissue left her tall enough that she had to hunch over to avoid hitting her head on the ceiling, and she was lying down. Half of it was angry, red, wrinkled or blistered. The other half was smooth tissue, dark greens, dark brown and pale grays. The head of an animal, half-bovine and half-canine, extended from the front, large as a horse from the back of its skull to the tip of its flaring nostrils. Another head was in progress, emerging just to the left. Two forelegs extended to either side of the heads, rippling with powerful muscle, ending in something that fell between claw and hoof, massive and easily capable of tearing through steel.

There were the fingers and thumb of a hand, extending from her right hindquarters, each digit thicker around than Krouse was, with another, smaller limb extending from the palm. Her rear left hindquarters featured only a mess of tentacles, some bearing partial exoskeleton, some long enough that they had to encircle the massive head and numerous limbs, or wind in a wreath around her as she lay down, lest their coiled mass fill the master bedroom of the house and leave Krouse nowhere to sit. Despite the apparent lack of bones, the tentacles were capable of supporting her weight.

She didn't expel waste. She only grew, or she reinforced what had already grown.
