She isn't potty trained yet

Willow Park was doing her best to hype herself up today. She had to present her Abomination to the class at Hexside, and she wasn't as confident as her classmates, much less the star student Amity Blight.

"You can do it. Even if you get a bad grade, it's not a reflection of you as a witch. And my parents are right. There are better opportunities on this track. Now get to school!" Willow tried to be inspirational, but as she was giving her little speech to herself, she realized she accidentally crushed an innocent flower. "Oh no! Little friend, I'm sorry!" She squeaked out as she struggled to heal the flower with her plant magic.

While she was kneeling down to heal the aforementioned flower, the skirt on her school uniform was hiked up a little, giving anyone who came this way a good look at her flower-printed diaper.
