The Black Seas Barracuda is the iconic pirate ship of Captain Jack Knife and his band of pirates. Captain Jack Knife became captain of the Black Seas Barracuda after losing his former ship, the Rosebrick, to his arch-nemesis Admiral Perriwinklebeard McCook. With this mighty pirate ship under his command, he proudly plundered the seas of the LEGO Universe. However, the greedy pirates stockpiled crates full of Maelstrom Crystals aboard the Black Seas Barracuda, which caught the attention of the Kraken. The giant sea monster grabbed the Black Seas Barracuda and tossed the pirate ship into a tree at Pirate Cove.
