Yes. Believe it. I have tiny penguins on my nails. ON-MY-NAILS! PENGUINS! CUTENESS! Haha. I saw this either on someone's tumblr or Instagram a while ago (wish I could remember!!), and I just had to try it! It looks a bit messy, but I'm satisfied with how it came out for the most part.
I used Skin Food nail polish in Ice Milk for the base of all my nails. For the penguin I used any white polish I had kicking' around (this one's from H&M), and for eyes I put a glob of Chanel Black Satin on a piece of paper, and used a pencil to dot the eyes. The yellow details were done the same way in Sally Hansen Instadry in Lightening. For my non-penguin nails I used Sephora for OPI in Flurry Up. Then I put a top coat on everything! Easy, peasy, lemon-squeezy!
