Peppermint is a human. They aren't freaking out too much because they are used to transformations, and being a candevil gave them gender euphoria, so they don't mind it much right now.
The start start is missing because I didn't like how it looked, but basically is Peppermint being hit mid cassette swap, from a plant bootleg to a fire bootleg, and then falling into the water, then washing up on shore face first onto the ground, with their broken cassete player next to them.
But because of the Mystery Dungeon portal magic they won't transform back into a human, because there aren't any cassettes in the player.
Peppermint is technically dual element, plant and fire, but because those are not the pokemon types, it behaves differently. Still thinking about it.
I'm still thinking if I should be treating elements and types as different things. But I probably will, going with the idea of fusion and it taking a toll on peppermint when they fuse with a pokemon for too long.
Candevil even if its base element, beast, would maybe translate to a normal type. They look more like the steriptype of a dark type (evilish), and that there is prejudice towards dark ghost types.
Peppermint is playing along with the amnesia thing until they know enough.
