Original Description:
 
Maud Pie has come home from college and Cloudy Quartz isn’t pleased with what she’s been told. Trouble studying, nearly failed two classes, and has been caught breaking campus rules. Maud is going to be spending her break grounded; no TV, going straight to her room after chores for studying, and a bedtime spanking every night. And she’ll be under constant supervision. Cloudy Quartz also thinks an additional punishment is needed since Maud has NEVER acted out while under the Pie Family Roof and now as an adult, she’s acting like a bratty teenager.
 
So she’ll be spending her time at home under Pinkie Pie’s supervision as her babysitter. Maud protests; I mean, she’s an adult. But Cloudy told her to either accept this punishment or she can be an adult and pay rent.
 
Pinkie Pie was more than happy to take up the role of disciplining her elder sister!
