This is a house made of water. The only things that are not water related is the bed, the chests, the bookshelves, the lantern which light up the houses, the crafting table, and the table with four chairs. This house is made for fun, not for survival. So please do not spawn mobs and then run to this house. You will certainly die. If you want to spawn mobs and make a bigger house with this world that is fine. That is up to you. If you want to download it and do whatever i dont mind. If you spawn mobs in the water house, just use a weapon like the rocket or a sword to protect you.
