This doesn't exist in Minecraft; it's just fictionSplash Centipedes or Marine Centipedes are Centipedes that are hostile and Boss like creatures that are found in many places but mostly at Underwater Strongholes and Under Ice in very deep Icy areas and Water Biomes. All of them are 10 blocks tall and very big and destructive. They love Water and is Fire Resistance (but can still be killed in lava).
They are very destructive like all the other centipedes (exept the Wither Centipede and cannot destroy Ice). This is the only Centipede that does not need to be spawned. When killed they drop 2 Bucket of Waters and Ice.
