This mod adds a few new Coralstone blocks (originally from Upgrade Aquatic) that are hosting deep warm sea corals (from Spawn). These new Coralstone blocks function just like the ones from Upgrade Aquatic: just place Coralstone near the corals from Spawn and let it rip. The mod also includes a datapack to integrate Spawn and Upgrade Aquatic's features a bit.

List of Datapack Changes (excluding those for the new blocks)

  • Raw Bluefish, Herring, and Tuna are included in #c:foods/raw_fish
  • Blue-footed Boobies now pick up any item in #c:foods/raw_fish, which includes the raw fish items from Upgrade Aquatic

    • This is a temporary measure and will be removed when Spawn updates.
  • Bluefish will attack Nautilus, Perch, and Pike when in a frenzy; they can also be enraged by raw Perch and Pike items
  • Pigment Shifters can be crafted with Luminous Prismarine
  • Sea Cows like Pickerelweed, and can be bred with Boiled Pickerelweed.
  • Seals will eat raw Perch and Pike items.
  • Tuna will eat raw Perch and Pike items.
  • Blasted Sand can be generated using a bubble column below Blasted Sandstone.
  • Thrashers will target Angler Fish, Barracuda, Blenny, Bluefish, Coastal Crab, Herring, Marine Iguana, Pilot Fish, Seahorse, Seal, and Tuna
  • Nautilus will spawn in Deep Warm Ocean and Seagrass Meadow.
  • Items in Bottles found in oceans can now contains Thrasher Teeth and Driftwood Boats
  • Sea Cows can now commonly dig up the corals from Upgrade Aquatic.

    • Since the number of corals in this loot pool has effectively tripled, I also tripled the rolls for every non-coral item. Hopefully you won't be drowning in corals.
  • Sea Cows can now rarely dig up Thrasher Teeth.

If you run into any bugs or have ideas for more constructive bridging between these two mods let me know in the issues page.

Thanks to Team Abnormals for Upgrade Aquatic, where the new Coralstone blocks get their code and textures, and for Blueprint which this mod's code relies on. And thanks to Peculiar Room for Spawn, where the new blocks get their palettes from.
