What? Bullshit! Remember when it showed what she looked like from the mr Hiragi's perspective AFTER she had gotten the level up and she still looked like a floating root?
Still, it wouldn't be hard for her to get another upgrade. After all she's a plant, an innately magical plant that god the power of the fairy ring. Plants grow, and magic can manipulate how they grow. Therefor she could become more like one of those plant monsters you see on /d/ where they have a sexy body growing out of their buds.
