Greetings.
I am a man in a suit who has fallen into the world of Minecraft.
Our ocean creeper farm uses three floors that meet at the center, where the drops are processed and collected in a chest.
Here, I follow that connection through the real screenshots.
The story of finishing the build is in OjiCra Season 3 Episode 80.
Here, let us follow the mechanism from the three ocean floors to the chest through the photographs.
The three ocean floors connect through the first-floor water channel and drop holes from the upper floors, then through the central shaft, soul campfires, and hoppers.
The last chest image shows 327 gunpowder, one bone, and one arrow.
Three ocean floors leading toward the center

Three circular floors are stacked over the ocean.
In this build, they do not lead to separate collection points: each one connects to the same central route.
Building over the ocean was a location choice for OjiCra.
It does not promise the same result everywhere.

On the first floor, a water channel runs from the arms of the floor toward the center.
The screenshot shows creepers on the floor and the blue route that carries them inward.
In this build, the channel bottom is three blocks below the first-floor surface.
The first thing to watch is whether the water keeps moving toward the central shaft.
The two upper floors use drop holes in the same position, rather than water channels, to reach the first floor.
Bringing the three levels together lets the lower mechanism stay in one place.
In this farm, open trapdoors at the floor edge lead to a deep water channel on the first floor and drop holes on the two floors above.
Giving the channel and holes separate destinations makes it easier to bring all three floors toward the center.

Trapdoors line the ceiling, while creepers are visible on the floor.
In this farm, the ceiling is kept low to limit the space available to taller mobs.
Carpet on the floor reduces the area where spiders can spawn.
Minecraft’s trapdoor introduction explains their basic opening and closing behavior.
This is the arrangement chosen for this farm. It is not a promise that only creepers will spawn here.
Processing the route below and catching it with hoppers

What reaches the center travels down the shaft toward the soul campfires below.
Behind the glass, blue flames and the hoppers beneath them show the processing section.
Here, the drop is followed by soul-campfire processing, and the hoppers send the items to a chest.
After building, I also check that each hopper points toward the chest.
If the chest stays empty, I first look for water flowing toward the center.
Then I check that the hoppers point into the chest.
Minecraft’s hopper introduction explains that hoppers can catch items from above and move them down or sideways.
This farm uses that behavior to connect the collection point to its chest.
327 gunpowder visible in the chest

The chest shows five stacks of 64 gunpowder and another seven, for a total of 327.
One bone and one arrow are visible beside it.
This farm’s chest shows 327 gunpowder.
Output can change with the location, edition, and how a player waits, so this one image is the result we can see here.
Minecraft’s gunpowder introduction notes that gunpowder can be used for firework rockets.
For a man who travels with an Elytra, seeing it collect in a chest is a reassuring sight.
The three ocean floors, water route, drop-and-processing section, and hopper collection connect in that order.
If you try a similar shape, check the water flow and each hopper connection one at a time, and confirm a design that suits the edition you play.
That is all for this time.
Greetings.
