From Batman Inc no.4. A mysterious and powerful ring around the world, 'the serpent eating it's own tail'. Grant Morrison is crafting a story that stretches right back to the Silver Age. Super spies, Nazi scientists, criminals, a mad old man feeling the web from a remote South Atlantic island and an ultimate weapon 'Oroboro', powerful enough to "blow a hole in the world". So, south Atlantic island and penguins, which means judging by the art that these little 'happy feet' must either be Adelie or Rockhopper penguins.
