Smack The Penguin!
This one could keep you occupied for hours. It's certainly a
way to get rid of your aggression. This is also really good for improving hand-eye coordination and timing.
So, how far can you smack the penguin?
Click to make the penguin jump and then click again, in time to
make the Yeti swing the bat to hit the penguin across the ice!
