Bloons is possibly one of the biggest hits of the internet flash gaming world, spawning numerous spin offs that let people play dozens, if not hundreds of levels. The Christmas Expansion edition in itself is not to be outdone. While the rules may seem familiar (launch the darts, pop as many balloons as possible, don't run out of darts) the Christmas theme makes the game all the more merry. The new levels, as well as Christmas themed music and graphics make this dart launching monkey very jolly indeed. If it was real winter, the bloons would be exploding from cold!
