Mad Cap Mushroom
The Night Goblins make this mushroom into beer so strong it'll make you vomit. They force-feed it to gobbos before a fight and then tie a big ball to them. If they swing it anywhere near their friends, they're getting wrecked by Gork.
That gobbo threw up after drinking the Mad Cap Mushroom beer.
My friend got smacked by Mork because he swung the ball too close.
The gobbo looked like a madman swinging that ball around.
