Getting there and back¶
The Knock-Up Stream¶
A Knock-Up Stream is a geyser on the floor of the deep ocean. There is one for every island in Skypiea, beside it below: a crater of dark prismarine and tuff round the Knock-Up Core.
An eruption¶
| Phase | Default | What happens |
|---|---|---|
| Quiet | the rest of the cycle | a bubble column marks the geyser |
| Charge | 30 seconds | bubbles and rumbling: the warning |
| Eruption | 90 seconds | the column rises to the sky |
A cycle lasts ten minutes by default, and each geyser is offset in it by its own position: two geysers rarely erupt at the same moment. All three lengths are in the configuration.
The column lifts whatever is caught in it: players, mobs, dropped items, and boats with everyone aboard. At the top it sends them on to Skypiea. An eruption always lasts long enough to carry somebody from the sea floor to the top, whatever the configuration says.
The arrival¶
You come down on the ground or on the cloud sea, never inside a block. On an island with a village, the geyser sets you down in front of its Heaven's Gate; a boat arrives with its riders still in it.
The express shrimp¶
Sail up to Heaven's Gate in a boat with a player aboard, and the express shrimp comes up under it: it takes the boat on its back, carries it through the Gate's tunnel and along the causeway, and sets it down on the sea by the island's seafront, crew still aboard. It is free, as the Gate is. A boat still in the air from the geyser is not taken: let it settle on the cloud sea first.
The way back¶
Step off an island and sink through the cloud sea. Below the bottom of Skypiea you come out high above the same place in the overworld — over the sea, since Skypiea only lies above the deep oceans.
- Falling on your own, you get slow falling long enough to land safely.
- A boat comes back with its crew, and falls. Without a balloon octopus the landing is a hard one: everyone aboard is hurt by how far the boat fell — half a point a block, about ninety points for the whole way home, armour counting — and the boat breaks and gives its item back.
The height of the fall back is return_y in the configuration.
The balloon octopus¶
Click a boat with a balloon octopus before you leave the sky: it takes hold of the boat, and when the boat falls it swells and brings it down slowly — six blocks a second — all the way to the Blue Sea. Nobody aboard is hurt.
- One fall only: the octopus lets go on landing, and is gone. One that never served (its boat lost on the way) gives itself back.
- A short drop — off a quay, off the shrimp's back — does not use it up.
- Sold by the waver dealer of an Angel Beach, two to four at a time, for 150,000 to 250,000 extols. It is in no chest.
- A player who leaves the game while the boat comes down, someone else still aboard, is put back in the boat on coming back — or let down slowly if the boat has landed meanwhile.
For operators¶
| Command | What it does |
|---|---|
/geyser |
where the nearest geyser within 64 blocks is, what it is doing and when it erupts |
/geyser now |
makes that geyser erupt at once |
Server builders can also place a geyser of their own: the Knock-Up Stream block, on the Configuration page.
