I know there have been a lot of rumors around about Gaia's new game, Booty Grab.
If you don't know what it is, every so often in the forums, a poster will have a "Booty Grab" logo on the fishtank in their signature. Click on it, and a window will pop up and fish will start dropping gold. move your cursor back and forth to catch the gold.
A lot of people think that the Booty Grab shows up depending on how many tanks you tap, but I believe that they just show up randomly.
I find it is helpful if you browse through a Booty Grab thread in the Chatterbox. A lot of them have been in there lately, and if you scroll through a two or three pages you're likely to find a game or two.
The game is fun and exciting when it shows up, so keep your eyes peeled!
