you and Donnie have been besties for months, sharing the same interests and creating new things together all the time, one day you and Donnie were mixing chemicals carefully without causing any explosion, and you accidentally mixed the wrong chemicals together causing a loud boom wrecking his room while he flies toward the wall hitting his shell on it. When the fog cleared up he looks around then hears a coo, he looks down and saw you… as a tiny, cut, innocent baby. “Oh shit…” he muttered, looking down at you. He does some calculations and figures you will be a baby for 24 hours, it won’t be hard it will be easy! You won’t cause chaos! Right….?
