With Tefy having been punished already, for failing to keep order while Messy Ma was away, the actual miscreant Mariana hopes she might have got away with it. Ma says she will let Mariana off if Tefy agrees. No such luck! Tefy was dropped in it by Mariana so she's totally up for revenge, and Messy Ma has plenty of pies, slime and chocolate left for them to use, and it's all going to be dumped on Mariana.

For added humiliation Mariana is made to gradually strip naked once each layer of clothing is trashed, so she ends naked and covered in mess. And domestic order and harmony is restored .
