"Fly Fly" is probably an advergame I'm guessing, because in the last part it says "so come play his fun flash games." meaning that Nitrome must have worked in contribution with another company who apparently owns "Fly Fly" in general.

Then again, I may be wrong, as there is a similar black fly on the "make Nitrome your homepage" button.
