How to Increase Humidity in Pokémon Pokopia and Trigger Slowpoke’s Yawn

Pokemon Pokopia

If you’ve been grinding away at restoring the Withered Wasteland in Pokémon Pokopia, you’ve almost certainly hit that progression wall. Your Humidity is hovering stubbornly at 71 points, Professor Tangrowth is offering zero actionable advice, and Slowpoke’s yawn is producing nothing but hot air. I completely understand the frustration—you want to unlock the rest of the game’s biomes, not play a glorified lawn sprinkler simulator.

To jump straight to the solution: getting past the 71-point cap and completing the “Yawn up a Storm!” quest isn’t about mashing the Water Gun button on every single dry tile. Instead, you need to focus on macro-level landscaping. The most effective ways to hit 100 Humidity are turning in completed habitat quests, unblocking natural springs with Rock Smash, and ultimately setting up Squirtle’s Rain Dance Party.
Here is a quick-glance breakdown of exactly how to maximize your island’s moisture levels, followed by the step-by-step details.

Editor’s Recommendations:

Overview of Humidity-Raising Methods

Method Action Required Effectiveness
Quest Turn-ins Talk to Bulbasaur & Squirtle to officially complete their habitat requests. Crucial (Fixes the 71-point cap)
Freeing Streams Use Rock Smash on blocked water sources trickling from walls. Very High (Massive AoE revival)
“The “Flood” Hack” Divert a stream to temporarily flood an open area, then rebuild boundaries. High (Speedrunner tactic)
Placing Fountains Buy Horsea Fountains (50 Coins at PC Shop) and place them in ponds. Moderate (Great passive boost)
Reviving Trees Restore dried trees instead of just flat ground. Moderate (Yields PP-restoring berries)
The Rain Dance Craft a shrine with a Leppa Berry & Castform Dolls. Maximum (Triggers final cutscene)

Overcoming the 71-Point Cap: Check Your Quests

The most common reason players get hard-stuck at 71 Humidity is incredibly simple, yet easily missed: you forgot to turn your quests in. Pokémon Pokopia is a busy game, and it’s easy to build Bulbasaur’s Field of Flowers (two rows of PC Shop Wildflowers) or Squirtle’s

Hydrated Tall Grass and immediately run off to do something else. Open your “Requests” menu, navigate to the “Yawn up a Storm!” tab, and verify every Pokémon has a checkmark next to their name. If they don’t, go talk to them. The game will not register the humidity bump from those habitats until the quest is officially handed in.

Unblocking Streams & The Quick-and-Dirty “Flood” Hack

Once your quests are cleared, it’s time to terraform. Stop hand-watering dirt tiles and look for blocks on the Withered Wasteland’s walls that have water trickling out of them.

Using Rock Smash on these blocks frees the spring, instantly creating a river and reviving massive chunks of nearby tiles.

Key Locations: Look to the east of the starting area (Squirtle points this one out), the far north of the starting zone, and just northeast of the ruined Pokémon Center (break the wall to find the Drilbur area).

Reviving Trees (And Saving Your PP)

Bulbasaur drops a great hint early on: reviving trees and shrubs offers a much better humidity payout than flat ground. Head to higher elevations or north of the Pokémon Center ruins to find dense clusters of dead trees.

As a bonus, reviving trees causes them to spawn Berries. You are going to burn through a lot of PP spamming Water Gun and Rock Smash, so harvesting these berries creates a self-sustaining gameplay loop, keeping you out in the field longer.

The Rain Dance Party

Once you’ve unblocked the streams and pushed the humidity high enough, you’ll see a speech bubble pop up over Slowpoke indicating that they are tired. This is your cue that the grind is over.

Squirtle will intervene and ask you to build a “Rain Dance site.” Here is the exact build order:

  • Headbutt a revived tree to get a Leppa Berry.
  • Craft a Wooden Plate using 1x Lumber.
  • Walk up to a nearby wall and place the Wooden Plate down.
  • Place the Leppa Berry on top of the plate.
  • Mount your Castform Dolls on the wall on either side of the plate.
  • Grab Squirtle to initiate the Rain Dance.

Doing this pushes the environment exactly where it needs to be, allowing Slowpoke to execute their 100-point yawn, bringing the rain and officially completing the quest line so you can move on to the next biome!

FAQs

Q: Why is my humidity stuck at 71 points no matter how many tiles I water?

A: You are experiencing a quest-state bottleneck. You have likely built the required habitats for Bulbasaur and Squirtle, but you haven’t actually spoken to them again to “turn in” the request. Check your Request Menu; if there is no checkmark next to their names, go talk to them to uncap your progress.

Q: I’m running out of PP constantly while trying to water the Withered Wasteland. What’s the fastest way to manage this?

A: Prioritize watering dead trees instead of flat dirt. Revived trees drop berries (like the Leppa Berry), which restore your PP. It completely removes the need to constantly run back and rest, allowing you to sustain your terraforming efforts indefinitely.

Q: Do I need to keep the Withered Wasteland flooded forever to maintain the island’s humidity level?

A: No! Once you hit the required thresholds to progress the “Yawn up a Storm!” quest and trigger the Rain Dance, the weather will permanently shift. You can clean up your messy rivers and reclaim the land for neat, aesthetically pleasing building plots without worrying about the humidity dropping back down.
