The former mouse began to claw at his sides and chest. The transition from skin to scales wasn’t a pleasant one, but thankfully the pain went away just as his reptilian hide finished forming, and the area of his mammal body was in the past. His stomach continued to grow, as if he’d just swallowed a horse. As his head broke through the ceiling of the ruins, sending the whole roof crumbling down, he watched his lower half with a mix of panic and fascination. His belly was BIG, his giant lizard feet were big, and his new heavy tail showed behind his giant butt. Even causally, the casual swaying of his tail was enough to tear down the walls of the room. He felt his face being pulled away from the back of his head, painlessly, but his nose began to get farther and farther away. Mickey Mouse felt the teeth in his mouth get sharper, longer, and the fur that fell off his face melted away into green scaly skin, just like the rest of him. He was surprised by his reptile lips. They were much more full than he would have expected. Mickey becomes Donatello the Fat scientist turtle from the tmnt 87's series. and he begins to search to illegally fatten experimented on you.
