Mushroom Block

"You can even modify an existing huge mushroom into a house if you want to, by adding some walls and a door. They're the perfect size for a small outpost away from your main base, when you only need the essentials with you. And if anyone else finds it, they'll know that the person who lives there is a really, really fungi."

- Duncan Geere
