Them waters be filled with booty!! Pretty frickin' awesome shirt!! There's actually a lot going on here. A pirate giraffe, riding his noble shark-steed looking for treasure and adventure. As seen here, in the narwhal formation, The giraffes sword serving as the tusk. They are fairly unstoppable in water. Due to the giraffes long neck, his head would be still above water when the shark is under, enabling both to breathe at the same time. Quite an effective killing machine. Thanks for the epic shirt, secret reddit santa ....whomever you are.
