Walkthrough

Finish Piplup’s request with Paldean Wooper in Bleak Beach before attempting the drink-based water tools. The drink determines the liquid produced; hold ZL to adjust placement height and attach the source to a block or existing water.
Plan the terrain before releasing a source. A primary source feeds the flow; removing it removes the water it supplies. Water reaching a drop can create a secondary source, so check the terrain below as well as the original placement when tracing a stream.
Use fresh water beside fields when you want hydration and sparkling ripples. Muddy water and lava do not hydrate, ocean water has no ripples, and a submerged ordinary plant stops growing. Water Gun turns lava into Black Rock; lava can damage Ditto.

Type	Practical use or caution
Fresh Water	Hydrates; sparkling ripples can appear.
Ocean Water	Sparkling sea water; no ripples.
Muddy Water	Does not hydrate; no ripples.
Hot Spring Water	Residents may relax in it.
Lava	Does not hydrate and damages Ditto.

Situation	What to check
A field remains dry	Check the liquid type: muddy water and lava do not hydrate.
Water is covering a plant	Reshape the channel or remove the source; use adjacent water instead of submerging the crop.
