I found some more bat the penguin games (mostly variations on the original theme, but some are different enough to be entertaining for more than a few thwacks.)

I found a list of the variations which include:

• Yeti Pingu-Throw
• Yeti Pingu-Throw (Bloody)
• Yeti Pingu-Throw (Long Shot)
• Yeti Orca Slap
• Yeti Seal Bounce
• Yeti Albatros Overload
• Yeti Flamingo Drive

A similar game launches kittens instead of seals and another one called Nanaca crash uses an Anime girl on a bicycle to thwack an Anime guy, who curls up into a little ball as he bounces along. It’s all very entertaining.
