If you are experiencing horrible lag in the ocean biome of Genesis then it is most likely because hundreds (literally) are cranes in a crevasse of the ceiling of the terrain. These crevasses are all over the place underwater.
Heres a funny story. I had a pet fish named BOWSER we went everywhere together. By the water of course. But one day I found a dilo and he destroyed BOWSER. So I shot him with my shotgun and declared war on silos. RIP BOWSER😭
Coelacanth the water type pokemon, known for it's small size and outstanding power this pokemon can destroy any creature in its path by launching like a torpedo and exploding on contact, considered to be a WMD by the Canadian and US military
if u ever see one run away. it might use its laser fish eyes or maybe its tail slice. if you see one and want to tame it, u need at least 20 max lvl gigas and 35 max rex. to tame get a titan and use cannons. at least 100 cannon balls will do. make sure to keep the titan far enough away so it doesnt get killed. once its knocked feed it the sacrifices one by one. it will probably take 15 hours to tame so put on a diaper and take a seat. i hope tgis is helpful. up if helpful
