Smack the Penguin

It's time for Yeti batting practice, and his friend the penguin has volunteered. Help the Yeti hit the penguin as far as possible. Click once to get the penguin to jump, then click and release to swing the Yeti's club and smack the penguin. Note that the penguin will go farther if you can get him to bounce along the snow.

My Smack the Penguin record so far is 588.8 -- Can you do better?
