Pegasus,

I typed your name into the Fairy-Name-Finder and this is what came up.

Your fairy is called Fidget Elfdancer

She is a cheerful sprite.

She lives in rotting woodlands near poisonous toadstools.

She is only seen when the bees swarm and the crickets chirrup.

She wears red with white spots, like the toadstools.

She has delicate green wings like a cicada.

And she let Petunia win the thread war.
