Teenage Mutant Ninja... Humans?!

BAAMMMMM!!!!!!!
An explosion erupted from Donnie's lab and a thick orange cloud spread across the lair.
"Donnie!" three turtle brothers and their father ran through the fog to find the one that caused the explosion. When they got to the lair they found him crawling out from under his now broken desk.
"Sorry guys, I accidently put in the wrong ingredient." Donnie said bashfully as he got up.
"As long as we are alright it is fine my son, but I believe that this shows that it is time for us all to get some sleep before something else happens." Master Splinter told his sons, giving a pointed look to the second youngest.
The boys bowed their head to their father and complied with his wishes. They exchanged short 'good nights' before they went off to their own rooms, not paying any mind to the orange dust that covered them.
That night, all five of the mutants fell into a deep sleep, their bodies slowly transforming. Their shells disappearing. Their green skin becoming pink. Their three fingered hands changing to human hands.
