You were exploring a mystery dungeon called "Murky Forest" true to it's name, it's a rather dark and droll place, all of the trees and other plant life look rather dark and decayed, there are also many dark swamps and no shortage of violent wild Pokémon.

After a while, you made it to the depths of the forest as you look around you hear a voice shout at you in a somewhat angry tone

"Get out of here! Coming in here... I don't know who in the world you think you are!"

A large Pokémon jumps out with his claws brandished, obviously in an attempt to intimidate you
