Sweetie Belle is one of Scootaloo's best friends ever, so when the little unicorn filly begs her to tag along to their clubhouse for a secret fun she knows, Scootaloo doesn't think too much of it. Unannounced to Scootaloo was exactly what they'd be doing, or simply wearing, for fun.
Diapers!? This is what she wanted us to do, wear these?? We aren't foals for crying out loud! Even for Sweetie Belle, this shouldn't seem so normal. Ugh! She couldn't possibly make this any weirder...
