The 'Percy Jackson: Sea of Monsters' trailer is finally online after it popped up in theaters attached to screenings of 'The Host.' (No more low-res leaked versions for you.) Your favorite trio of demigod heroes are back for another adventure.

In this second installment of the Young Adult novel-adapted storyline, Logan Lerman returns to the screen as Percy Jackson, the son of the Greek God Poseidon, along with his pals -- Alexandra Daddario's Annabeth and Brandon T. Jackson's satyr sidekick Grover. After traveling to Hades and back in the first film, the trio now must dive deep through the Sea of Monsters, known more commonly as the Bermuda Triangle. Their home/training grounds, Camp Half-Blood, is threatened by the titan Cronos, and only the Golden Fleece has the power to stop him.

As the first trailer (via reveals, new (and old) enemies and allies will be introduced along the way, including Stanley Tucci as the leopard print-wearing Dionysus and 'The Hunger Games' star Leven Rambin as Clarisse, the daughter of Ares. Not to mention, fans of Greek myth will get a kick out of seeing live-action interpretations of classic monsters, like the Charybdis (aka the giant whirlpool with teeth).

Some of the footage looks like a 'Harry Potter' cheesefest, like that taxi cab "chariot," but we're still excited for this nonetheless. Check out the first 'Percy Jackson: Sea of Monsters' trailer below, and let us know what you think in the comments.
