Thie story takes place after the episode Baby Cakes

Pinkie Pie is left in charge of caring for the Cake Twins for an entire week. But somehow while Pinkie was feeding the foals she didnt realise that the muffins she fed them had chaos magic left behind by Discord. Soon Pinkie Pie was regressed into a baby and the Cake Twins are now adults and are scared of getting in trouble. So they try to care for Pinkie Pie and open Suagrcube Corner on their own. But this could be too much for the twins as they learn being an adult is much harder then they thought.
