Worried that his pirates are growing bored with a life of winking at pretty native ladies and trying to stick enough jellyfish together to make a bouncy castle, the Pirate Captain decides it's high time to spearhead an adventure. While searching for some major pirate booty, he mistakenly attacks the young Charles Darwin's Beagle and then leads his ragtag crew from the exotic Galapagos Islands to the fog-filled streets of Victorian London. There they encounter grisly murder, vanishing ladies, radioactive elephants, and the Holy Ghost himself. And that's not even the half of it.
