Just in case anyone hasn't heard me talking about penguins, I collect them. I love them. They're cool! Most of the time I try not to force my obsession on others. But hey, today is World Penguin Day. It's my duty to post one of my favorites, "Humboldt penguins chasing a butterfly!"

Butterflies have to be strange creatures to penguins. I mean, you don't see a whole lot of butterflies in Antarctica! So when a pretty yellow one wandered into a zoo, the penguins couldn't help but chase it. Of course, they don't run very fast! But that's okay. The butterfly keeps coming back to say hello. It's a very cute video. Happy World Penguin Day!
