Seafoam Islands

Navigate the treacherous Seafoam Islands in Pokemon Let's Go Pikachu and Let's Go Eevee. Discover wild Pokemon, trainers, and hidden items across multiple floors.

This chilly dungeon divides Route 20 into two. They say a Legendary Bird Pokémon has made its nest here. We can vouch for that.

Wild Pokémon

Floor 1F

As you arrive from the Fuchsia City side, you’ll start near the south-west corner. Head east to begin with. You’ll go past a Picnicker who’s just here to offer some advice. To her north-east is a stone block next to a hole in the floor. Face the block from the left side, then use the Strong Push Secret Technique to push it into the hole.

If you accidentally fall through the hole, don’t worry. In fact, if you’re in a hurry, you can purposely jump into the hole after you’ve pushed the block through. Otherwise, stay on this floor so we can have a look around. Return towards the entrance, then proceed north, up the slope to higher ground. Grab the Ice Heal to the left.

Just ahead is a ladder going down to B1F. Ignore it for now. If you’re in a battling mood, go to the north-west corner. Over here, there’s a Coach Trainer.

Coach Trainer Yas

Yas has got all the Eevee evolutions found in Kanto. Jolteon has exceptional Speed, so don’t be alarmed if it outspeeds you. It can use Thunder for heavy STAB damage, Double Kick to hit Rock-types etc. and Quick Attack to go first. Ground-types are obviously the safest choice.

Vaporeon has formidable special bulk, so physical attacks are recommended. It has a similar moveset as Jolteon, but replace Thunder with Hydro Pump. As such, Grass-types are the way to go if you want to minimize damage.

Finally, he’s got a Flareon that’s geared towards physical attacking. This one also has Double Kick and Quick Attack, but has Flare Blitz for STAB. Water and Rock-types are advised to reduce the damage from Flame Blitz. Unless you’re confident you can outlast it.

Emerge victorious and you’ll be given 5 Rare Candies. Moving on, head east for a while. Along the way, pick up the Escape Rope. If you get lost here, you can use that to make a timely escape. At the end of this higher ground, there’s a kind man who will refill your Poké Balls if you’ve ran out. Head down the nearby slope.

Over in this corner, there’s another stone block near a hole in the floor. Approach the stone block from above or below, then push it down or up one space. Next, push it left three spaces. Finally, shove it towards the hole. After that, you can jump into the hole or go down the nearby ladder like a normal human being.

Actually, before going downstairs, search the rocks directly above the ladder. You should find a Heart Scale.

Floor B1F (north-east)

Downstairs, grab the 5 Great Balls from the floor. Next, approach the stone block from its right side and shove it through the hole on the left. If you want, you can jump through the hole to reach B2F. However, you might notice that there isn’t a ladder going back up. So instead, we recommend going back up to Floor 1F. But it’s up to you.

Once you’re upstairs again, head back to the north-west corner and go down the ladder that you walked past.

Floor B1F (main)

These caves run quite deep.

You’ll start left from the center, on a section of higher ground. Go south, down the slope. Keep going until you reach the wall along the bottom, then go up the slope on the right to reach another area of higher ground. Grab the Super Repel to the left of the slope. Up ahead, there’s a ladder going down. Go past it, towards the east.

Down the next slope, you should reach the first stone block that you pushed–the one nearer the west side. If you jumped from the hole, you’ll also land here. In any case, shove the stone block into the hole on the right. Afterwards, you may follow it down the hole. Or you can go back and head clockwise from the first ladder on this floor.

In the north-west corner, there is a ladder going down. Before going down the ladder, grab the Max Potion to the right.

Floor B2F (north-west)

After going down the ladder, search the rocks near the bottom-left corner. You should find another Heart Scale. Hang onto this for later. Next, go east. Over here, there’s the first stone block again. Use Strong Push to nudge it into the hole directly to its right. If you’re courageous, you can jump into the hole after doing so.

However, this time, it’s a bit riskier. If you fall through this hole, you’ll end up plunging into water on Floor B3F. If both of the stone blocks from 1F haven’t reached B3F, the rapid currents will push you towards the north-east corner of B4F. Instead, we recommend going back to Floor B1F. Then go down the ladder near the center.

Floor B2F (main)

You’ll arrive near the center. Head south-west, down the left hand side slope, towards the far corner. There’s a ladder here that you can use to continue downstairs. By the way, if you go east from here–or south east from where you arrived–you’ll come across a ladder that goes upstairs. But
