This is the Bulbapedia walkthrough for Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!.
These pages follow the remade Nintendo Switch iteration, not Pokémon Yellow. The guide for that game can be found here.

Cinnabar Island

Cinnabar Island

Cinnabar is a large island to the southwest of mainland Kanto, between Routes 20 and 21. The Cinnabar Lab, where researchers have developed a way to revive ancient Pokémon, stands to the west. A broken-down building known as Pokémon Mansion is located on the island's northwest side. The Cinnabar Gym can be found to the northeast, but is currently locked up tight.

Pokémon Center

Time for a Trade

A Punk Guy to the right of the counter is looking to trade Pokémon. He wants to get a GrimerP / MeowthE and is willing to part with its Alolan counterpart in exchange. Alolan Grimer is a Poison/Dark Pokémon, while Alolan Meowth is a Dark-type Pokémon. Dark types are few and far between in the Kanto region, so either one can make a useful addition to your team. This trade may be conducted multiple times.

Cinnabar Lab

Reception Room

In the Reception Room, Scientists meet visitors to the lab and unwind when they are not working.

Research Room

In the Research Room, speak to the Scientist seated at the desk to receive TM02 (Taunt). When used, Taunt lures the target into using only damaging moves.

Testing Room

Fossil Regeneration

The Scientist near the back wall runs the fossil regeneration procedure. Speak to him to hand over the Helix Fossil, Dome Fossil, or Old Amber. The procedure only takes a moment to complete, and you soon receive the ancient Pokémon. The Helix Fossil and Dome Fossil become Omanyte and Kabuto, respectively; both are Rock/Water Pokémon that swam the primordial seas. The Old Amber becomes the Rock/Flying Aerodactyl, a terror of the prehistoric skies.

Pokémon Mansion

The Pokémon Mansion is the decrepit, burned-out former home of a famous Pokémon researcher. The building uses several hidden switches to lock and unlock doors, and Burglars prowl the ruins for valuable items. A series of journal entries can be found scattered around the mansion that describe the birth and escape of a genetically-engineered Pokémon.


Go to the northwest room to find a Max Repel, then inspect the stone statue with pulsing red eyes to flip a hidden switch. Head east, then turn south at the four pillars; pass through the newly-opened door to reach a Max Elixir in the central room. Continue to the east side of 1F to find a Max Lure sitting under a table. Return to the entrance and climb the stairs at the end of the entryway.


Follow the hallway to the southwest room to find the first journal entry and a PP Up. Return to the stairs and inspect the nearest statue to flip the switch. Follow the hallway to the southeast balcony this time to reach a set of three Ultra Balls. Visit the west-central room to battle Burglar Arnie and grab a Max Ether. Climb up the nearest stairs to reach an isolated part of 3F.

3F (Southwest)

A second journal entry can be found here. Defeat Burglar Simon and pick up the Rare Candy before returning to 2F.


Go northeast to find a third journal entry, and a Max Revive in the northeast room beyond that. Turn around and go south from the room with the journal to reach an Escape Rope. Visit the northwest room to fight Coach Trainer Rita, who gives out TM22 (Rock Slide) when defeated. Climb up the nearby stairs to 3F.


Head east to find a Full Heal behind the statue, and pick up TM21 (Foul Play) in the northeast room. Go back to inspect the statue and flip the switch; this closes the north door and opens the southern one. Battle Scientist Braydon and grab the X Accuracy at the end of the east-central hallway. Take the stairs to the south to an isolated part of 2F.

2F (East)

Battle Ace Trainer Louis, then pick up the Hyper Potion to the north. Take the stairs back to 3F.


Climb down the ladder to the southwest of Scientist Braydon. This leads to an isolated part of 1F.

1F (South)

Pick up the set of five Silver Razz Berries near the ladder. Battle Scientist Ted, then continue south past the row of potted plants to get a Fire Stone. If you need to leave the mansion early, there is a warp tile in the room to the east that leads just outside of the entrance. Otherwise, take the stairs down to the basement.


Fight Burglar Lewis and visit the southern room to collect TM52 (Sludge Bomb). The final journal entry can be found on the table here. Go west to grab the Max Potion. Inspect the statue and flip the switch. Follow the hallway to the northeast room; if your Pokémon need medical attention, you can rest on the three beds here. Inspect the nearby statue to flip the switch and continue along the hallway to battle Scientist Ivan. Collect the Rare Candy in the north-central room, and the Max Elixir near the large glass container in the northwest room. The Secret Key is located in the final room to the south.

Cinnabar Gym

Cinnabar Gym

Cinnabar Island Pokémon Gym
Leader: Blaine

The Hot-Headed Quiz Master

The Cinnabar Gym specializes in Fire-type Pokémon. Fire-type moves are super effective against Grass-, Bug-, Ice-, and Steel-type Pokémon, while Fire-type Pokémon are weak to Water-, Rock-, and Ground-type moves. When playing with fire there is always the chance of getting Burned, so be sure to bring some Burn Heals.

Upon entering the building, you are greeted by the Gym guide. He is about to explain the Gym but is interrupted by an old man, who excitedly tries to quiz you right off the bat. The guide reminds him that it's not yet his turn, and Blaine takes his place farther ahead. There is no requirement to challenge the Cinnabar Gym, as the guide says that finding the Secret Key was difficult enough.

The Gym Leader is always thinking up ways to keep the families of the Scientists who work on the island from getting bored. Blaine enjoys riddles and has designed his Gym as a quiz show, complete with stage and TV cameras. Speak to him at the end of the red carpet to begin his Pokémon Quiz. Challengers are asked five questions, with each correct response earning them a Blaine doll that appears on the stage. Incorrect answers mean a battle with one of his students, who also give out a doll when defeated. Collect five Blaine dolls to challenge the Gym Leader!

Cinnabar Gym
The Volcano Badge

After the battle, Blaine awards you the Volcano Badge, which ensures obedience of all Pokémon up to level 80. He also gives you TM46 (Fire Blast) as a prize.

When you leave the Gym, Trace is standing near the sign. He congratulates you on your victory, and reminds you that you need eight to reach the Pokémon League. Only one more to go! Even though it was locked up the last time you visited, he suggests checking out the Gym back in Viridian City.

With the Cinnabar Gym defeated, surf north from the pier to reach Route 21.

Route 21

Route 21

Route 21 is an ocean route that leads from Cinnabar Island back to Pallet Town. A single patch of tall grass grows just outside of town.

Pallet Town

Having now explored nearly all of the Kanto region, it is a good time to tie up any loose ends, the most important of which is the Power Plant. To get there, use Sky Dash to fly off to the Pokémon Center on the north side of Route 10.

Route 10 (North)

To reach the Power Plant, use Sea Skim to follow the river southward past the Rock Tunnel entrance. It is only a short distance away, with a single Poké Maniac outside the building.
