Cadance: Oh my, looks like some ponies need a bath.



Dash, Fluttershy and Rarity: *in unison* oh snap!



*the trio try to escape, but Candance grabs them all telekinetically, takes Rainbow Dash and Fluttershy's diapers off, and starts floating the 3 fillies over to a conveniently prepared bathtub*



Cadance: And I see you've managed to take your diaper off already, Rarity, way to think ahead!



Rarity: uh, well yes, of course! *chuckles nerviously*
