I'm too lazy to code and make this pretty. Evergardens will be open to the public until the blizzard gets nasty, and then things will start to go awry!

People might get trapped in any of the rooms
Someone could get caught in an endless loop of walking like they're just going round and round in circles >D
Plants could get cranky and cold, and want warmth from any passersby
Animals could freak out: quails could apparate anywhere inside the greenhouse without meaning to

Go forth! >D
