The not so popular ocean biome seems to me to have a LOT of potential, if worked well,you could make it 100% more interesting than a giant body of water.Everything ( mostly,resides underwater)
Lets start with items. 1.1 ITEMS
1.1.1 Diving Helmet : First of all, as I said before,underwater is the most interesting part of the ocean, so , as you may see, if you go underwater you get a really dense fog that blocks visibility in a higher percentage.... so the most reasonable idea to get rid of this fog is using a special helmet, just like in real life to see better underwater and also, combined with an air tank, to extend your breathing greatly.
1.1.2 Air Tank : This air tank its iron made , very strong, it can hold big cuantities of air. Right now I dont have a specific mechanic to fill this with oxygen, but it will fill up everytime you return to surface ( or an air pocket)
1.1.3 Fluorecent torches: This special torches are made to iluminate underwater, its crafted with slimeballs , and Coral dust (since they are slightly luminicent)
1.2 Blocks (New and old(tweaked))
1.0.1 Sponges (yay!): This block, unobtainble right now could have the perfect oporunity to reappear in Minecraft, and recover its functionality.The sponge would be naturaly encountered in coral reefs and other coral formations.
1.2.2 Algae : This block would be found specially near coral reefs and over moss stone, algae can reach 3 blocks high ,and it would have uses in alchemy when smashed.
1.2.3 Moss stone : This is a new block that will normally appear in ocean biomes at almost any height of the ocean , this block has similar texture as smoothstone but greenner and mossier , the block is slippery.
1.2.4 Coral : This block is generated in small groups at a relatively deep, in groups of 5-10 mixed with algae and smoothstone , Coral has 3 different colours (not decided yet which ones)and attract underwater fauna. This blocks are luminicent. They can be smashed to get Coral dust.
1.2.5 Shell: This block is home sometimes for some animals so beware when you break it , they appear in different sizes , 1x1 , 1x2 and 2x2.The utility of shells is yet not determined.
3. Terrain Changes
3.0.1 Deeper Ocean: The ocean needs certainly to be deeper 20-30 block deeper , to have more space for all the content , but its gradual, normally parts of the ocean near to land are often higher than mid sea that is deeper.
3.0.2 Sunken Temples : This would be the third dungeon like construction that would appear in game,it would be very similar to a stronghold , using the brick blocks as its main composition but mainly cracked and mossy bricks. The temple would have an entrance deep in the ocean flooded obviously, but with underground half flooded corridors as well as other important features , probably to make it more interesting, the ability to summon the kraken(ocean boss).
3.0.3 Pits: This pits would be large height depresions in sea floor that would be 30-40 block deeper than normal , although this ocurrence is rare. This would be the home of the summoned kraken. Visibility is severely reduced in this pits.Dangerous mobs wander this place...
3.0.4 Underwater caverns: This caverns are caverns flooded or semi-flooded that spawn near oceans,they are essential to the ocean exploring since these are potential bases due to their air pockets.They are normally made of stone,moss stone and vines.
3.0.5 Sand plains : This sand plains are tranquil places where a lot of animals have their home,crabs , special fishes and even sharks are here.
3.0.6 Icebergs and Glaciers: This ice formations can be naturaly encountered in ocean biomes near snow biomes (ill make a suggestion about these later on more deeply)
3.0.7 Shoreline: This shoreline is an effect the appears when ocean water is right next to a sand block (horizontaly) to make the beaches much prettier :smile.gif:.
3.0.8 Coral Reefs : Already mentioned before . :smile.gif:
3.0.9 Rocks : These rocks naturally form near beaches and any place where the ocean meets land.
4. Mobs & Animals :
4.0.1 Sharks: One of the ocean's danger , they are aggresive to sight and they will drop Shark skin and 1 shark jaw ( 1 shark jaw = 9 shark teeth)
4.0.2 Octopus: This would be squid's older brother, when killed they would drop 4-6 ink sacs and octopus tentacles that would be used for alchemy.Hostile.
4.0.3 Dolphins : This mob is friendly but goes hostile if attacked, they can be tamed with raw fish ( 3-5) and they would be ridable .
4.0.4 Crabs : These creatures lurk in beaches and underwater in the sand plains,they are neutral-hostile, when killed they drop pincers that can be used just as shears but with a lot less use.
4.0.5 Mollusk : This small creature often lives inside shells, they can be killed in the moment of the destruction of the shell or be alive and angry at you and attack you. They drop molusk meat, that can be cooked to be edible.
4.0.6 Swordfish : These special mob with its sharp end its hostile and when killed drops Fish's sword that can be used as a normal sword with stone-iron durability/strength.
4.0.7 Sea Turtle : This animal lurks deep in the sea and likes to swim over pits, when killed they drop turle carapace that can be crafted into armor ( iron - diamond durability but decreases speed considerably)
4.0.8 Sea Dragon: This animal its komodo dragon's aquatic counterpart, they have 4 legs and wander in the sand plains, they drop scales, that can be later on crafted into armor(better durability than leather , but not better than iron, it increases speed slightly)
4.0.9 Whale : This big , colossal animals is normally found in the middle of the sea, they are strong, but slow. When killed they drop whale oil, that can be used to make braziers and better quality torches.
4.1.0 Stingray : this flat specimen is commonly found hiding in the sand in the sand plains.If you aproach, they are hostile, if you keep your distance, they are neutral.When killed they drop stingray poision,that can be used to enchance arrows and weapons.
4.1.1 Abisal fish: This is one of the few animals that live in the pit, they are usually wandering around with their light above their head. They are hostile. When killed they drop 1-3 fish fang (no use yet) and a light gland(when placed it doesnt emit light but when powered with redstone it works)
4.1.2 Sea Lions: Sea lions are often encountered near the rocks in the sea and over them,taking sun, some of them wander, but they live in communities. They can be tamed if given fish. They can also be killed to obtain their oil and fangs, but if done so, you scare the whole community.
4.1.3 Kraken : These old monster,very big, its encountered in the bottom of the pit, he cant move from hes spot.He has long tentacles that can be streched all the pit up, but not all of em.He is very hard to kill, but first to be killed he must be called from an underwater temple.Only one kraken exist per ocean biome. They posses very valuable loot since they have destroyed whole ships and boats. Killing him grants an achievment.To be summoned they need to be gathered 7 Orbs of the sea that are obtained from each temple ( 7 temples per ocean).
4.1.4 Sirens: These enchanting creatures live in the sunken temples of the sea, they guard their proper orb of the sea.
