There is now an abyss biome which is an ocean which goes down to bedrock and the water turns dark black. There is no light except for luminescent shrimp which look like glowing orbs. When left clicking on them they disappear but when using a bottle of water you get a luminous bottle. The bottle gives off light for 3 minutes, then it turns back into a bottle of water. Angler fish are a new mob. They disguise themselves as the luminescent shrimp until you get near them, then they attack you. Towards the bottom giant squids will spawn rarely (they won't have a boss bar) it will look like a giant red squid. It will attempt to drag the player down and kill them. The Giant squid is afraid of conduits, Once killed the giant squid will drop the abyssal pearl. The abyssal pearl glows in iem form so players can find it. When the Abyssal pearl is in a players hand (or off-hand) it lights up the area around the player infinitely.
