I thought I should write some backstory for flippy, and explain his motives. Yeah...
On a boring day in a boring month of a boring year, in a boring colony of penguins on the Falkland Islands, a mother and father looked down at their egg. A tiny beak pecked its way through the shell and was followed by a tiny fluffy bird. Then the adorable newborn chick murdered its parents.
Flippy's bloodthirst continued as he grew up, and he spent his childhood tricking explorers in to stepping on unexloded land mines and chasing them off cliffs.
One day, when flippy was munching on an explorer's liver, he had a sudden realisation. He decided that his destiny was to murder annoying bad guys and get tv characters to hook up. He hitchhiked his way across time and space, leaving a trail of blood and shipping in his wake.
Flippy never forgot his true love, a female penguin from the colony. As soon as he was nearby, he came back to the colony to court her. Unfortunately she had been shot by an explorer so Flippy got over her and went off to turn Hamlet into an orgy.
Look, he's a murderous time travelling storyhopping penguin. What the hell did you expect? A normal plot?
