Appendix:Let's Go, Pikachu! and Let's Go, Eevee! walkthrough/Section 17

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.

Pallet Town


When you reappear in your room, your partner happily gifts you the Small Bouquet it made. As you attempt to go downstairs, Trace rushes into your room with rumors of a strong-looking Pokémon spotted near a cave in Cerulean City. He intends to make it a competition between the two of you, and whoever catches the Pokémon first wins.

A World Expands

Stepping outside, you realize that your world has expanded after becoming Champion. The coveted title brings new privileges, so you can now fly through the sky on Charizard, Aerodactyl, or Dragonite whenever you like! This allows you to encounter other Flying-type Pokémon high in the skies, and also lets you bypass areas that require Chop Down or Sea Skim.

As you reach this realization, a Youngster calls out to you. He reintroduces himself as Ronny from Route 1, and informs you that Master Trainers have now appeared all throughout Kanto. These elite Trainers have spent their entire careers training one specific Pokémon species, and will not be easy to defeat! There are 153 of them to find, and they can be identified by their red clothes and the speech bubble above their head that shows their chosen Pokémon. When battling them, you may only use a single Pokémon and it must be the same as theirs. Their Pokémon are high-leveled and well-trained, so defeating them all will not be easy.

Cerulean City

There is only one place left to explore: Cerulean Cave, a mysterious place on the northwest edge of Cerulean City. To get there, visitors may use Sea Skim to sail southward from Route 24, or simply fly over the water with a Flying-type Pokémon. The Coach Trainer who had initially blocked entry to the cave has moved aside, and can now be battled like any other. Defeating Coach Trainer Harjit earns you TM60 (Megahorn).

Cerulean Cave

Cerulean Cave is a mysterious cavern located in the northwest part of Cerulean City. Only the most powerful Trainers who have entered the Hall of Fame are allowed to enter due to the powerful wild Pokémon inside. The sprawling cave network is unforgiving, so be sure to prepare well. Pack the Super Rod and stock up on Ultra Balls, and bring the Master Ball as well. It is here that the genetically-engineered Pokémon from Cinnabar Island's Pokémon Mansion fled after escaping the facility.


Head to the water's edge and use Sea Skim to reach a PP Max on the island in the northeast corner. Ignore the nearby and ladder and continue surfing westward. At the west end of the water, you can reach dry land to the north and south. Climb the hill to the north to get a Max Repel, then head south along the ridge or the water to find a Full Heal. Turn eastward and continue along the central ridge in a counter-clockwise direction to pick up a Max Revive on the north side. With the first floor cleared, you may climb either nearby ladder to reach 2F.


The second floor is one large, open chamber. Be sure to collect the several visible items that are scattered around, including treasures like a Rare Candy and a Max Revive. There are also several glowing spots on the ground that mark the potential location of other hidden treasures. To continue through the cave, climb down the ladder in the northwest corner.

1F (Northwest)

Take the next ladder down to the lower floor.


Go east along the ridge and walk down the hill. Continue along to the northeast corner, where an Escape Rope can be found. Head south along the east wall. From the southeast corner, turn north and climb onto the central ridge. Move north to reach a Full Restore, then go west. Head south and zigzag a bit to reach a Max Elixir near a patch of glowing crystals. Use Sea Skim to reach the southwest island and find Mewtwo, alone on its island. Like with the legendary birds, Mewtwo will reappear if defeated or run from after you enter the Hall of Fame again.

VS Mewtwo

Not only is Mewtwo the strongest Pokémon around, but it has already reached level 70. As a Psychic-type Pokémon, it is best to use Bug-, Ghost-, and Dark-type attacks to lower its health quickly. The Legendary Pokémon can restore its health repeatedly with Recover, so inflicting status ailments like Sleep and Paralysis are useful to limit its movements. Mewtwo will not let itself be caught easily, so either use the Master Ball immediately after it is defeated or be prepared to go through more than a few Ultra Balls. When the battle is over, use an Escape Rope to quickly exit the cave.

Still Hunting a Legend

When you exit the cave, Trace rushes up to you from the west. He's impressed that you have captured Mewtwo, but disappointed that you beat him to it. He tells you that he ran into "some gutsy girl" who was looking for a powerful Pokémon, and must have gone into the cave. With Mewtwo captured, Trace isn't interested in exploring the cave anymore, and gives you his three Escape Ropes instead. He thinks that the girl is likely still looking for Mewtwo, and suggests going back to show her.

Cerulean Cave

Make your way through the cave again to return to Mewtwo's island on the lower floor. On the north side, you find a girl standing with her back to you. Speak to her, and you are suddenly hit with a low-flying Poké Ball! She apologizes for mistaking you for a Pokémon, and introduces herself as Green. She asks if you are also here looking for "something special", and is upset to learn that you have already caught the Genetic Pokémon, and so challenges you to a battle!

VS Green

After the battle, Green accepts that Mewtwo belongs with you, and hands you a pair of items as a reward: the Mewtwonite X and the Mewtwonite Y. With these Mega Stones, Mewtwo can now Mega Evolve into one of two forms during battle, boosting its aleady-high stats to incredible heights! The girl has an idea, and jokingly asks if you would like to become her Pokémon alongside Mewtwo. She even throws several Poké Balls at you! When she's had enough, she runs off, leaving you free to collect the five Poké Balls that she left behind.
