Minecraft will receive an influx of new underwater content this week, and more slated to arrive in the near future, as we continue down the road to Update 1.13 (or the Update Aquatic if you’re a Steve Zissou fan). Additions include seagrass, kelp blocks and an equippable trident. But Minecraft’s new turtles will probably absorb the most attention from the community.

It’s always exciting when Mojang adds new content to Minecraft. The sandbox game is very mod-friendly and the community has added plenty to it over the years. Still, millions of gamers prefer “vanilla” Minecraft. Now, they finally have more reason to spend time exploring large bodies of water than the ocean monuments added in 2014. Longtime Minecraft developer Nathan “Dinnerbone” Adams says more aquatic content is on the way in upcoming snapshots. Mojang still hasn’t determined the final slate.

Snapshot 18w07a also introduces the Phantom, formerly known as the Monster of the Night Skies. The flying, manta-like creature will spawn at high altitudes and prey on players who go “many days” without sleeping. Phantoms currently drop leather, which suggests they aren’t meant to be especially tough to fight. However, Mojang says that reward could change in the future, presumably in response to feedback from the Minecraft community.

Here are the complete patch notes for Minecraft snapshot 18w07a:
