Piranhas are some dangerous fish, man. Particularly if you're a balloon. Or a disco ball. OK, so I can't full explain the concept behind Piranha Pop, but it goes something like this: Use your mouse to aim the piranha, hold down the button to charge it up, and then fire it into the air. The object of this oddball cannon physics game is to bust as many balloons as possible in the air, while still taking down that pesky disco ball. The fewer fish you fire, the better. Chomp away, disco-hating fish, chomp away!
