No real animals were harmed in the making of this game...I think

Continuing in my penguin state of mind, I was tipped off to this great time-waster: "Penguin Batting." My longest HR so far is just over 450 feet.

Yetis slamming penguins...is there nothing this internet cannot do???

ENJOY!

Update: Longest now 488.3! Beat That...
Update 2: 491.4! Woohoo...
Update 3: 574!!!
Thanks, Neopuritan for the hint...
