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:
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.
