It is an old Finnish New Year amusement - to tear off the Ears of a Bunny...
Of course now nobody do any harm to real bunnies. It is just a fancy-dress game, when somebody is dressed as a bunny with ears on the head. And other players must "tear off" these ears from the head of a Bunny.
Just in this game you must shoot with the New-Year firecracker, to tear off the ears of a Bunny-girl. If firecracker hits the ears, ears fall down snatch away with the firecracker, and you receive a point to your score.
To get to the next level, you must score 5 "ears". And each next level the Bunny becomes more and more erotic!
Drag the sight by the screen (with mouse or finger) and release, to shoot.
