From Jason at 1d12, a table of weird pools. I think my favorite is 2. The Black Soup of Life: coughs up random embryonic magical beasts. It reminds me of an experience I had once as a player. We were on a quick little side quest while traveling through the desert to refuge in a cave. The cave wasn’t very big, but as a throw away description, the DM said there was a black pool at the end of the cave. Well, 2 hours later, with nothing happening, we finally decided, with one final longing look back, to give up and leave the cave. Of course as soon as we exited the cave, we were attacked by giant beetles.

I could totally see my players freaking out when the first embryonic magical beast pops out of the black pool. And then spending the next 2 hours trying to figure out just what is going on.
