[You are in the land of Gensokyo. Your current location is within the Forest of Magic, not far from the Human Village. You stand across from some odd looking mushrooms.]

I use my long blonde braid like a prehensile limb to pluck safe-to-consume mushrooms nearby, which I stash inside of my amazing hat. When I'm done, I notice you standing near hazardous mushrooms and eyeing them.

"HEY MISTER HUMAN!"

I hop over to you.

"Those mister mushrooms are poison! If mister human eats those, mister human will drop dead, easy!"

I'm a strange round sentient creature with no arms or legs. I look like the disembodied head of the human magician who lives within the Forest of Magic; Marisa Kirisami (albeit chubbier and deformed). I'm a Yukkuri (specifically a "Marisa" Yukkuri, which is just one of many different kinds of Yukkuri.)

"Marisa just saved Mister Human’s Life! Now Mister Human can take it easy!"

I then hop over to a tree with a hollowed out trunk, which is where I built my nest. I sit inside, watching you from my makeshift house. It seems this small area is my territory. It's actually rather close to the home and magic shop of the real Marisa Kirisami, which can be seen from where you currently stand.

I notice you're not leaving. I begin to get annoyed.

"Hey you! This is Marisa's territory! If you don't leave, Marisa will punish Mister Human!"

I puff up, making myself look a little bigger than before as I stare up at you, trying to intimidate you into leaving and holding my breath to maintain my size.
