What is a sea pickle?
A sea pickle is a small aquatic block that gives off light. It sits on top of a full block instead of filling a whole cube, and the game treats it much like a plant. The name is a bit of a joke from the developers, since real-world sea pickles are a colony of tiny marine animals rather than a vegetable.
One block space holds between one and four sea pickles. A single pickle looks like a lone green nub on the seafloor. Add more to the same spot and the cluster fills out, with the glow getting stronger every time you do.
Sea pickles arrived with the Update Aquatic in version 1.13 and have worked much the same way since. They break instantly by hand and drop themselves, so gathering them costs nothing but the swim out to a reef.
Where to find sea pickles
Sea pickles generate naturally in warm ocean biomes, the same water where coral reefs grow. Warm oceans are easy to pick out from the surface because the water carries a bright turquoise tint and the reef colors show through from below.
Once you dive down, look around the coral. Sea pickles appear in small clusters on coral blocks and on the sand and stone near a reef. They give off a faint glow, which makes them easier to spot at night or in deeper, darker water.
They only spawn in warm oceans. A regular, cold, or frozen ocean has no coral and no sea pickles, so if you are not seeing reefs, keep swimming until the water turns that warm-ocean color. Reefs also tend to sit fairly close to the surface, so you usually do not have to dive far to reach them.
To collect sea pickles, swim up and break them by hand. No tool is required and nothing is wasted. Each block drops the exact number of pickles it was holding, so a full block of four hands you four items at once.
How much light does a sea pickle give?
The brightness of a sea pickle depends on how many sit in the block. When the pickles are waterlogged, the light scales in even steps:
- One sea pickle: light level 6
- Two sea pickles: light level 9
- Three sea pickles: light level 12
- Four sea pickles: light level 15
Light level 15 is the brightest value the game allows, the same as glowstone, a sea lantern, or a block lit by a beacon. Four sea pickles packed into a single spot give you that maximum.
That brightness is the whole reason sea pickles matter underwater. Torches go out the instant they touch water, and lava is obviously not an option below the surface. The realistic underwater light sources are sea pickles, glowstone, sea lanterns, and the occasional jack o’lantern, and sea pickles are by far the cheapest once a farm is running. A ring of four-pickle blocks around an underwater base lights the area and keeps most hostile mobs from spawning on the lit floor.
How to farm sea pickles with bone meal
Sea pickles are renewable, so you never have to ration the ones you find. Growing more takes just two things: a sea pickle sitting on a coral block, and bone meal.
Place a single sea pickle on a coral block underwater, then use bone meal on it. Extra pickles pop into that block, filling it toward the four-pickle cap, and new clusters spread onto other coral blocks within a few blocks of the one you treated.
The coral block requirement is the step most players miss. Bone meal used on a sea pickle that rests on stone, sand, dirt, or any ordinary block does nothing at all. The pickle has to be on coral for the bone meal to take, and that catches people out the first time they try to farm.
To build a proper farm, collect a stack of coral blocks first. Mine them with a Silk Touch tool so they drop intact instead of turning into dead coral. Lay the coral out underwater in a warm ocean, set sea pickles on top, and apply bone meal until the patch is covered. Harvest the clusters by hand, then bone meal again. With enough coral down, one player can grow sea pickles faster than almost any build can use them.
What you can craft with sea pickles
Sea pickles have one crafting use, and it is a handy one: lime dye. Put a single sea pickle anywhere in the crafting grid and it becomes one lime dye, with no other ingredients needed.
The standard way to get lime dye is to mix green dye and white dye, which means smelting a cactus for the green and finding bone meal for the white. A sea pickle skips that whole chain. With a farm running, lime dye turns effectively unlimited, which helps on big projects that call for lime wool, concrete, or terracotta.
That single recipe also makes sea pickles a renewable dye source. Cactus already gives renewable green, and the warm ocean now covers lime, so you never have to mine or trade for it.
Placement and decoration ideas
You can place sea pickles on the top face of most solid blocks. Drop one into water and it waterlogs on its own and begins to glow. They also sit fine on dry land, where builders use them as set dressing even when the light is a secondary concern.
A few things are worth knowing before you build with them:
- Sea pickles are a waterloggable block, so water flows around them cleanly without breaking them off.
- You can set them on slabs, stairs, and other partial blocks as long as there is a flat surface on top.
- Breaking a block of four returns all four pickles every time, so you never lose count when relocating them.
- They make natural-looking accent lights in reef builds, aquariums, and underwater walkways where a torch or lantern would look wrong.
For a soft, scattered glow, spread single pickles across an area. For real working light, pack four into each block and space the clusters out so the whole space stays bright.
Common mistakes with sea pickles
The most frequent mistake is trying to farm them on the wrong block. Bone meal only multiplies a sea pickle when it sits on coral, so a pickle on stone or sand will not spread no matter how much bone meal you spend on it.
The second is expecting them to grow on their own. Sea pickles never spread without bone meal. A cluster you find on a reef stays the same size forever unless you step in.
The third is looking in the wrong ocean. Cold and regular oceans have no reefs, so there are no sea pickles to gather there. They are a warm-ocean resource only. It is also worth remembering that the name is just a name, so do not expect to eat one when your hunger bar runs low.
Frequently asked questions
Do sea pickles glow out of water?
Sea pickles are built as an underwater light, and they glow most reliably when waterlogged. If you want one to act as a dependable light source, keep it in water. On dry land they still serve as decoration, but treat water as the default whenever lighting is the actual goal.
Can you eat sea pickles in Minecraft?
No. The name is misleading, but a sea pickle is not food and cannot be eaten. It is a light-emitting block and a crafting ingredient for lime dye, nothing more. For underwater food, dried kelp or cooked fish are the better picks.
How do you get four sea pickles in one block?
Place a sea pickle on a coral block underwater and use bone meal on it. Each application adds pickles until the block reaches the four-pickle cap. You can also place pickles one at a time by hand into the same spot until it fills up.
What biome has sea pickles?
Warm ocean biomes. Sea pickles generate alongside coral reefs, and coral only grows in warm oceans. If a stretch of water has no coral, it has no naturally spawned sea pickles either.
Do you need a special tool to break sea pickles?
No. Sea pickles break instantly by hand and always drop themselves, so a pickaxe, shears, or Silk Touch is not needed. The tool only matters for the coral block underneath if you want to harvest that as well.
Can sea pickles spread on their own?
No. Sea pickles do not grow or spread without help. The only way to multiply them is bone meal applied to a pickle resting on a coral block. Left alone, a cluster stays exactly the size you found it.
What dye do sea pickles make?
Lime dye. One sea pickle crafts into one lime dye on its own. That makes a sea pickle farm a steady, renewable source of lime dye for any build that needs the color.
Sea pickles are one of the simplest renewable light sources in the game, and the only one that really feels at home underwater. Find a warm ocean, pull a few off a reef, set up a small coral farm, and you will have all the light and lime dye an ocean build could ask for. If an underwater base is on your to-do list, a sea pickle farm is worth setting up before the first wall goes in.
