So it sounds like more mush for your team, congratulions
If it’s mushrooms and mentions “ring” specifically, it makes me think of those mushroom ring things.
Dunno if I’m thrilled about that, the other Poison type sounds more interesting.
Still would have liked a Fire/Poison based on the concept of burning garbage, or something based on a rat king.
No this is a fairy ring:
They’re a single spore that spreads tubes in all directions and forms caps in a circular pattern. Folklore belief is that fairies danced within these things so the poke may be based on a fairy surrounded by mushrooms.
