Batten down the hatches! A rowdy crew of sea rogues, led by a salty kraken, drifts through the waves, pilfering and plundering treasure from unsuspecting pirate ships. Once down under, the spoils are divvied up, because the best loot is shared loot!

    Aussie Aussie Aussie!

    This pair is so fun, not just for the olympics but the rugby that came to Australia too! Repping that green and gold is so much fun.
