Warm Ocean
Overworld (water)
A tropical sea with coral reefs on a sandy floor, sea pickles lighting the bottom and schools of tropical fish. Shipwrecks and warm ocean ruins hide between the reefs - and kelp refuses to grow here.

Resources
- Coral blocks, coral fans and coral of all five colors (mine with silk touch)
- Sea pickles - a placeable underwater light source
- Tropical fish and pufferfish (but no cod or salmon)
- Sand, seagrass and warm ocean ruins loot
Mobs
- Tropical fish (thousands of pattern variants) and pufferfish
- Dolphins - feed them raw fish and they lead you to ruins or shipwrecks
- Drowned, including trident drowners riding coral zombie nautiluses
Structures
- Warm ocean ruins (sandstone) with suspicious sand and treasure maps
- Shipwrecks between the reefs
- Coral reefs themselves - the biome's signature feature
Why go
- Coral for aquariums and tropical builds - silk touch mandatory, coral dies out of water
- Pufferfish for water breathing potions
- Treasure maps from the ruins, dolphin-guided
Tips
- Pufferfish poison on contact: keep your distance or empty-hand them into a bucket
- Sea pickles only glow underwater - pick them with anything, but place them wet
- A door or magma bubble column gives air pockets while you strip a reef
- Trident drowned here have a 50% chance to ride a coral zombie nautilus - a nasty ambush, so watch the reefs
