What it does

Upgrade Spawnquatic adds constructive compatibility between Upgrade Aquatic and Spawn. Several new Coralstone blocks host deep warm sea corals, and they behave like the Coralstone blocks from Upgrade Aquatic. Coralstone can be placed near corals that Spawn introduces, and the blocks take their textures and code from the mods they bridge. The Blueprint library supplies code the mod relies on. Spawn's palettes supply the block palettes for the new blocks.

Several aquatic creatures gain new behavior. Blue-footed Boobies pick up raw fish items, including the raw fish added by Upgrade Aquatic, and raw Bluefish, Herring and Tuna are tagged as raw fish. Bluefish attack Nautilus, Perch and Pike during a frenzy. Pigment Shifters are crafted with Luminous Prismarine, Sea Cows are bred with Pickerelweed, and Seals and Tuna eat raw Perch and Pike. A temporary measure removes some Spawn updates. A datapack can integrate further features of both mods. Upgrade Spawnquatic requires Blueprint, Spawn and Upgrade Aquatic. Installation covers the server and each player's game.
