Some fans draw her as a fluffy creature, called Sukusuku Hakutaku.
Since Perfect Memento in Strict Sense had mentioned that she was a teacher in a human village school, many fanart had showed her being a teacher in Gensokyo also, while some other touhou characters had been her students, like Cirno and Chen.
She is very often depicted giving headbutts. As a result, some fans tend to draw her giving headbutts as a punishment for naughty children in her class (which happens to be Cirno for obvious reasons)
In the fan game Gensou Shoujo Taisen, one of her attacks consists of giving a headbutt right up from the sky, resulting in an atomic explosion.
