Hamato Yoshi cried out in pain as a strange, glowing ooze hit his body. He crouched down, his hands clenched into tight fists, and he watched with both wonder and fear as his normal, human hands suddenly changed into three-fingered paws, his nails growing into sharp points. His face, too, was going through a transformation - his nose stretched out into a long snout, his teeth shifting about madly. Ears sprouted from the top of his head and he found he could hear a lot better. His clothes ripped apart and slowly tumbled to the floor, leaving him naked. Suddenly, he felt something growing quickly from his lower back. Eyes watering from the pain, Yoshi looked behind him, to find he had a long, pinkish tail - and it was still growing! His feet transformed into paws which looked much like his hands, and the rest of his body sprouted very dark, reddish brown fur. White stripes lined his snout. His eyes - once a deep, chocolate brown - were now a sort of red colour, and his eyesight was different, although only slightly but it was still noticeable.
Hamato Yoshi was finally relieved from the pain. He glanced down at his new body, and he let out a small gasp of shock. Yoshi was not human, but a giant, mutant rat! Yoshi steadied his breathing. He looked around the filthy alley - no sign of the glowing canister, or the twins dressed in black suits.
Yoshi looked down at his feet - no, his paws - and saw a baby turtle. One of the baby turtles he had just bought at the pet store, he presumed. The ooze had clearly hit the turtles, as well, as they were now toddling around on two legs, with two arms and three-fingered hands. Yoshi let out a small chuckle at the young one, stumbling about on his legs. Yoshi picked him carefully. The turtle had dark, blue eyes, and just from looking straight into those eyes, the rat noticed something rather... different about them. He pushed this to the back of his mind, for now at least.
Hamato Yoshi looked down at himself once more. Surely he could not walk around naked. There must be some form of clothing in this alley - in a trash can, perhaps? Holding the first young turtle closely to his new body, he slowly walked over to the trash can. He pulled off the lid and looked down. He saw what looked like a pair of dark red curtains, a pattern of three big flowers going down the side of them. Just his luck! Yoshi picked out the curtains with his free hand, put the lid back on the trash can and carefully placed the turtle on the top of the lid. The turtle sat down and watched with wide eyes as his new father tied the red curtains around his furry body. It seemed to resemble some sort of kimono - Yoshi was rather proud of himself. He grinned at the turtle tike and picked him up again, holding him tightly.
Yoshi saw something that caught his eye. Something was underneath an empty pizza box, and was making various types of noises whilst kicking at the box, trying to push it off himself. Turtle number one still firmly in his grip, he lifted up the pizza box with his free hand. As he lifted up the cardboard, Yoshi found that this was another turtle. The turtle, which had bright, green eyes, was still kicking with his eyes closed, even though the pizza box was off of him. Yoshi smiled and picked up the green-eyed turtle. The turtle stopped kicking and nuzzled deep into the giant rat's body, sucking his thumb as he did so.
'Was there not another?' Yoshi thought for a moment, furrowing his brows. There was definitely at least two more turtles hiding somewhere beneath all of this trash in the horrid alley. Yoshi placed the two turtles in the empty pizza box, closing the lid to keep them as warm as he could. He kept the lid open slightly so they could still breathe. He held the box tightly in his hand and shuffled around the alley. It was weird, walking on paws which had only three toes. Yoshi figured he would have to get used to that - he wasn't turning human any time soon.
There was scrunching noise coming from behind the mutant. He frowned slightly and turned around slowly, only to find a third turtle. The third one was looking very deep in thought, holding an empty chip packet in his two little hands. Yoshi tilted his head and grinned at the sight. This turtle had eyes like he did, before the mutation.
'Where could the fourth be?' Yoshi thought, placing the third turtle with the first two.
At least thirty minutes had passed before he found the fourth turtle. Yoshi was 99% sure that he would never find this one. The fourth turtle had freckles dotted around both his cheeks, and had lighter blue eyes than the first. Yoshi found him giggling behind a trash can. Obviously he found the game 'hide and seek' hilarious.
Once all of the turtles were in the pizza box, Yoshi wondered about where he could stay now. He certainly could not stay in this alley, surely somebody would come across a giant, mutated rat and four baby turtles.
And that's when he spotted the manhole lid, half open. He could smell the dreaded sewage already, but did he really have any other choice? He could go back to his house, but that meant risking his life. Almost everyone in New York City had a gun, be it a small pistol or a machine gun, and they would probably shoot at him and his four new adopted sons. If he went into the sewer, it would make life a lot easier for his new family.
Yoshi decided on the easy option.
Holding onto the pizza box tightly, he pushed open the lid using one of his paws and jumped down. He was an extremely skilled martial artist so he had no problem landing, even with his new rodent body.
He just stood there for a while, thinking. Thinking about how he would survive in the sewer with no food and only sewage water which would probably kill him in an instant. Thinking about how he would care for four mutant male turtle tots.
But if he could survive being mutated into a giant rat, he could surely manage bringing up four sons by himself... right?
