Appendix:Pokémon FireRed and LeafGreen Walkthrough/Part 20

## Seven Island

On the main part of Seven Island, there are no events. There is, however, a Poké Mart with the following items:

Head north and you'll be at the Trainer Tower.

### Trainer Tower

There is a a female Psychic immediately north.

Below her is a hidden Nanab Berry. Above her, down the ledge, is a male Psychic.

Surf up and you'll be at the main tower. Inside on the left is a Pokémon Center nurse and a PC. On the right is a woman who acts as a Poké Mart clerk and sells the following items:

They are the same items found in the Seven Island Poké Mart.

There are four different challenge modes: Single, Double, Knockout, and Mixed. Each challenge has eight floors and a battle on each floor. The battle information can be found on the Trainer Tower page. By winning each of the challenges, you'll win a prize:

Head back to Seven Island and go south. You'll be at the entrance to the Sevault Canyon.

### Canyon Entrance

On the bridge is a Move Tutor, who can teach one of your Pokémon Swords Dance. Head a little lower to face a Trainer.

Go around a little ways to face a Juggler.

Go down a bit more and you'll see two Pokémon Rangers, a male and a female, standing next to each other.

Head up onto the hill until you get off at the south, and you'll face a Young Couple.

Right above them is a hidden Rawst Berry. Go right from the two Pokémon Rangers and you'll soon be in the Sevault Canyon.

### Sevault Canyon

Keep going around and you can fight a Cool Couple.

Head just south to get a Nugget. Instead of going down further, head down the stairs into the little cave.

### Tanoby Key

This little cave is the Tanoby Key. All you need to do is push the boulders into the empty holes into the ground to trigger…something. You need Strength to do it.

Push the bottom two boulders into the bottom holes. Ignore the other ones right here and push the center of the three boulders all the way to the north hole. Go up and push the left boulder to the center, then push it up so it aligns with the top two holes and push it to the top left hole. Do the same thing to the right boulder. Go back down to the bottom two boulders. Push the left one to the center and align it with the remaining holes, and push it onto one of them, and repeat the process with the other boulder. If successful, you'll hear a rumble echo somewhere far away…

Head back outside.

### Sevault Canyon

Go back up on the mountain, and around. Go down and you'll fight a Tamer.

Below him in the corner is a Max Elixir. Head north and around, and you'll fight two Pokémon Rangers.

Go down and right and you'll face a Crush Girl.

Below her is a Strength and Rock Smash puzzle. Begin by smashing the bottom left rock and pushing the boulder all the way right. Smash the top rock and push the boulder down one tile. Smash the rock and move the boulder all the way right to collect the King's Rock, which can be held by a Poliwhirl or a Slowpoke to evolve it into Politoed or Slowking, respectfully, when traded while holding it.

Head down the stairs and face the Cooltrainer nearby.

Below him is a female Cooltrainer.

Right by her is a house with a man that'll heal your Pokémon with a dance. Afterwards, you can snag the Lucky Punch from the table. This will raise Chansey's critical hit ratio. Near the house outside is a hidden Cheri Berry.

Keep heading south and you'll be at the Tanoby Ruins.

### Tanoby Ruins

The Tanoby Ruins hold seven chambers with one of the seven Tanoby Chambers.

There are also some trainers here you can battle.

### Tanoby Chambers

From east to west, the Unown letters that appear are as follows:

It turns out that the Tanoby Key you unlocked earlier was the key to these chambers in order for the Unown to inhabit them. Catch some, then head back to Seven Island. Take the ferry back to One Island.

## One Island

Go to the Pokémon Network Center and give the Sapphire to Celio. He'll thank you and fix the machine. He'll be excited that he linked up with Lanette in Hoenn. Now you can trade with any other Generation III game, including Colosseum and XD.

Now you have one more task ahead of you. Go back to Vermilion City on the ferry, then fly to Cerulean City.
