It's not a joke.
The Skeinz yarn company put out a call for penguin sweaters in the Spring of 2011 and has a pattern for your knitters out there. Apparently, New Zealand penguins were affected by oil spills. They were cleaning themselves and ingesting the toxic oil. I read that they have enough now, but I had to show these little blue penguins wearing sweaters. Here's the link if you want to find out more. Penguin Sweater Link and this one here.
I think the purple wool shows off the penguin's coloring to her best advantage, don't you? But one wearing pom poms cracks me up.
Guess which penguin was the inspiration for the bead in my Etsy shop .... (the colors are truer to the real penguin's picture, but my camera is acting up)
