Well, two versions. The one on the left is the cute version - it mimics the standard Linux penguin pose and has a "who, me?" expression. The other one is a bit more to Lovecraft style but still harmless. Both have tiny dots of red enamel for their eyes.

Again, two versions since people cannot seem to agree on that one. To the left, the original branch-like version which in my opinion is a bit uninspiring, to the right the pentagram version every "Call of Cthulu" player should be familiar with.
