Imagine if......

The Creeping Doom was a 3-4 part episode. LIke what if Mikey's cure didn't work on Donnie and his intelligence kept deceasing over night and had the mind of a toddler. The the other turtles including April and Casey, had to re-teach him everything he knows while also trying to find a cure. It could've been like the episode Good Genes when Donnie turned into a monster and they had to get a cure for him right away. What do you guys think?????? - Slappy'sGirlfriend2598 P.S.
