Seaside Cave 1F

Head south to where the Battle Girl will be to your east. Move over and take her on!

Trainer Battle: Battle Girl

Pokemon Level Type
Heracross 47 Bug/Fighting

Head south down the steps and grab the Full Restore to the east. Head back up the steps and move back west past the Battle Girl. Move south and jump over the ledge. There’ll be a Pokemon Ranger here keen for a battle.

Trainer Battle: Pokemon Ranger

Pokemon Level Type
Vibrava 46 Ground/Dragon
Gligar 46 Ground/Flying

Before you jump over another ledge, turn on your Dowsing MCHN and use it to find the Blue Shard here. Now jump down the next ledge to your south. Continue in that direction and collect the Dive Ball as you move past it. Continue over yet another ledge. There’s a male Pokemon Ranger here. Feel free to take him on.

Trainer Battle: Pokemon Ranger

Pokemon Level Type
Onix 46 Rock/Ground
Lairon 46 Steel/Rock

Move south to the Black Belt who was guarding the entrance to the cave from Undella Bay. If you answer ‘Yes’ to his question, he’ll initiate a battle. If you win this battle, he’ll leave and allow you to freely move between Undella Bay and Seaside Cave.

Trainer Battle: Black Belt

This guy uses four, yes, four Roggenrolas.

Pokemon Level Type
Roggenrola 44 Rock
Roggenrola 44 Rock

Roggenrola 44 Rock

His Pokemon all have the Sturdy ability so expect to take at least two turns to faint each one, as Pokemon with Sturdy cannot be fainted if they have full HP. If you have Pokemon with Hail, Spikes, Stealth Rock, etc. you can get around this problem by constantly causing residual damage.

After you’ve ground his Pokemon to dust, head back north and take the bridge east. Follow it to the end, then follow it when it turns north. Head all the way back to the Battle Girl and once again jump over the ledge to her west leading south.

This time jump over the ledge taking you east. Move down the stairs and follow the path until you reach the water. Continue south and you’ll reach another Black Belt.

Trainer Battle: Black Belt

Pokemon Level Type
Scrafty 47 Dark/Fighting

The Black Belt will have blocked you from moving further south, but there’s nothing important there anyway. Instead, use Surf and move over the water leading east. There’s a little island with a Heart Scale on it. Grab the Scale then continue Surfing north.

You’ll eventually reach solid ground. Move onto it. You can now move up the steps leading outside, but you’ll need to battle a Crustle blocking your way first. It’s assumed that you’ll explore B1F first though. Head west and move down the steps to the floor below.

Seaside Cave B1F

Move south-west first. Continue down past the steps to the very bottom left corner of the floor. Now move through the gap and follow along the wall going east. You’ll find a Max Repel here. Now move back to the steps and move up them.

Use Strength and push the boulder into the hole. Continue over it and move down the steps. You’ll catch the eye of another Battle Girl.

Trainer Battle: Battle Girl

Pokemon Level Type
Mienfoo 47 Fighting

Continue past her and move up the steps. Strength will already be activated, so there’s no need to re-activate it. Simply push the first boulder west into the hole. Push the boulder to its north-west, north into the hole. Push the boulder north of that, north, then east into the hole.

Push the next boulder to its south, south into the hole. Push the boulder next to it east, then north into the hole. Grab the nearby Rare Candy , then push the final boulder into the hole to its north. Move over it and down the steps. Final battle for Seaside Cave, against another Black Belt.

Trainer Battle: Black Belt

Pokemon Level Type
Gurdurr 47 Fighting

Move up the steps leading back to 1F. Head west up the steps in 1F. You’ll see an item sitting snugly between two rocks. Grab it to find that it’s TM06 - Toxic . Now move back down the steps and jump over the ledge leading back south. Head up the steps to the east, leading out of the cave.

However as we mentioned earlier there’s a Crustle blocking the path. To make it budge you need to have obtained all 8 Gym badges, then receive the Colress MCHN from Colress in Route 22 . If you have it, interact with the Crustle and you’ll be given the option to fight it. Catch it if you desire.

Wild Pokemon Battle

Battling Crustle, the Bug/Rock Pokémon.

Pokemon Level Type
Crustle 42 Bug/Rock

Once the Pokemon’s defeated, move north and grab the Calcium hidden in the rock, then exit the cave.
