Shellos is one of the many Pokémon species who can join your town in Pokopia, but you may not know how to convince the Water type to move in right away.
Like other Pokémon, you’ll need to build the right home before Shellos will appear on the island. In case you’re after the Gen Four sea slug, here’s how to get Shellos in Pokopia.

How to befriend Shellos in Pokopia
Compared to some of the other Pokémon you’ll befriend, Shellos is a bit of a weird one. Instead of liking patches of grass or flower beds like other species, this Water type prefers signposts. Yup, that’s right. Signposts.
Why? Beats me. But what I do know is that I got Shellos to pop up by placing a signpost next to a wooden pathway, as shown in the image below. I picked up the signpost from where you find the Dowsing Machine in the mountainous area southwest of the Pokémon Center, so don’t worry about having to craft one if you haven’t unlocked the recipe yet.

Shellos is a rare spawn, so you’ll likely have to wait quite some time before it’ll show up. You can get both its pink and green versions to appear with enough patience. To help with the process, I placed a Security Camera close to the signpost, and it eventually informed me a Pokémon had appeared without me having to wait nearby.
How to raise Shellos’s comfort level in Pokopia
Once Shellos has moved in, they’ll ask you to make their home more comfy by raising its humidity. If you’ve already completed in “Yawn Up a Storm” mission, you’ll know some of the methods for doing so. If you haven’t, though, don’t fret—we’ve got you covered.
To raise humidity in Pokopia, you’ll want to do the following:
- Plant and grow flowers using Pokemon like Bulbasaur and Bellsprout
- Plant grass tufts using Leafage
- Dampen any nearby dry soil using Water Gun
You can also place a fountain or build a pond near the signpost to raise the environment’s humidity, but I avoided having to do that with enough flowers and grass. If you’re still having trouble getting Shellos’s home to be humid enough, check the image below. That’s what my Shellos’s home looks like, so I’d recommend making it look somewhat like that to reach the humidity requirements.

Is there a yellow Shellos in Pokopia?
Longtime fans of Pokemon know all too well that Shellos comes in two colors: green and pink. But if you explore the island well enough in Pokopia, you’ll eventually come across a discarded record titled “Shellos Report” that talks about a third type of Shellos, a yellow variant.
“Shellos changes its color and appearance based on diet and the environment it lives in,” the entry reads. “We are researching day and night in an attempt to create a heretofore unknown yellow Shellos.”


As of now, there’s no sign that anyone has found a yellow Shellos in Pokopia. Some fans have postulated that this excerpt might’ve been put in the game as a teaser for generation 10, Winds and Waves, which are slated for releases in 2027.
