How do I get to this leader, because I considered that I had walked all over the map and could not find him
Go to where you defeat the mushroom lady, after that glide down to the little spot that has like, a little pot and stuff there, go in the entrance, you'll see a character stick in the ground, by helping them, it'll trigger the boss battle
