Looking at the map, you discover a HUGE glass hothouse, used for growing plants and keeping animals in a jungle enviroment.
Deciding to go in, you discover two things;
1). It's not called a hothouse for nothing! you are forced to take your shirt offand wander around barechested.
2). It's much larger than it looks inside. You can't see any of the glass walls, just the glass roof high above you amplifying the heat creating a erm, greenhouse effect. You've been wandering for what looks like ages and you haven't encountered any walls, let alone exits since you came in here. "Hello?" you call "Anyone here?"
No reply. You must be the only one here.
Then, as you turn a corner you come across a large clear pool. It looks so inviting you want to strip off and dive in. After all, there aren't any signs up telling you not to, and you're all alone, so you can't see any reason not to go for a dip in the pool.
