   Summary

   Speed Demon is gone, but Donatello is still stuck in the form of a car. Without his body Donnie has no way of creating the retromutagen he needs to turn himself back to normal. Maybe Casey can check under the hood for him in the meantime...?

   Today we answer the question: Do cars have sexually charged dreams about their mechanics?

   Or as my beta describes this one: Shocking! You won’t believe how much this human cares for his mutant turtle-turned mutant car boyfriend. NOT clickbait.
