Calling all half-bloods! Disney+ has released the full trailer for Percy Jackson & The Olympians Season 2, and it looks like it’s going to be a watery good time.

Based on The Sea of Monsters, the second book in Rick Riordan’s beloved series, Season 2 reunites viewers with Percy Jackson (Walker Scobell), son of the Greek god Poseidon (Toby Stephens). After recovering Zeus’ (Courtney B. Vance, replacing the late Lance Reddick) Master Bolt and preventing a war among the Olympians in Season 1, Percy is headed back to Camp Half-Blood for the summer.

However, things are different this year. Percy’s satyr bestie Grover (Aryan Simhadri) has gone missing on his search to find Pan. To make matters worse, Kronos’ acolyte Luke (Charlie Bushnell) has poisoned the tree that keeps all of camp safe from monsters — the very same tree that Zeus’ daughter Thalia (Tamara Smart) transformed into prior to the events of Season 1. Now, Percy must head to the Sea of Monsters, aka the Bermuda Triangle, in order to find the Golden Fleece and save both Grover and Camp Half-Blood.

Accompanying him are Annabeth (Leah Sava Jeffries), the wise daughter of Athena (Andra Day); Clarisse (Dior Goodjohn), the hotheaded daughter of Ares (Adam Copeland); and Tyson (Daniel Diemer), Percy’s newly discovered cyclops half-brother.

The trailer teases massive nautical battles, new monstrous encounters, and even a glimpse at Thalia in action. Still no sign of what book fans are most pumped to see, though: Grover in that wedding dress.

Percy Jackson and the Olympians Season 2 premieres Dec. 10 on Disney+.
