Okay, so clearly my take on the game "Piranhas", not "Fish that Bite" (a title I made up), but I don't refer to the one you could find on Miniclips.

I used to play this around 10 years ago, but I don't think I can find the original. I remember the game as more pixelated but also allowed you to turn around the blocks...I think. In contrast to the one I mentioned first, that seems as if they digitally scanned a few things to add texture, and has wayyy more colors than I remember...
