How to Get Onix in Pokémon Pokopia

Onix is one of the most important Pokémon in Pokopia — its Bulldoze specialty is essential for rebuilding the Pokémon Center and relocating buildings. You'll unlock Onix by completing the "Yawn Up A Storm" main story quest in the Withered Wastelands.

Where to Find Onix

Onix is trapped in a cave northwest of the Withered Wastelands Pokémon Center, near the gate. You can reach the cave two ways:

• Use Rock Smash on the ground diagonally from Scyther's tree to reveal a cave gap
• Destroy blocks on the nearby road to reach the beach, which has another cave entrance

Follow the speech bubbles inside until you hear someone calling for help. You'll find Onix pinned behind unbreakable rocks.

Don't try to smash the rocks yet — they cannot be broken until rain softens them. This is the most common mistake players make.

Step-by-Step: Freeing Onix

Step 1: Talk to Professor Tangrowth

After discovering Onix, return to Professor Tangrowth. Escort them to the beach ruins for a group meeting with your Pokémon. The conclusion: you need Slowpoke to make it rain.

Step 2: Find and Attract Slowpoke

Build a Seaside Tall Grass habitat to attract Slowpoke:

• Place at least 4 Tall Grass blocks adjacent to the ocean
• Wait for Slowpoke to appear

Step 3: Guide Slowpoke to the Pokémon Center

Slowpoke moves slowly and cannot jump. You need to:

• Build stairs with varying heights for Slowpoke to navigate terrain
• Soak any cracked dry ground with Water Gun before Slowpoke crosses it
• Talk to Slowpoke if it stops moving — it will tell you what's blocking its path

Step 4: Raise Humidity

Slowpoke won't yawn unless the environment is humid enough. You'll see the message: *"Slowpoke tells you that it's too dry, so they're feeling very awake."*

Methods to raise humidity:

• Water dry ground with Water specialty Pokémon
• Plant seeds and flowers (Bulbasaur can help with Grow)
• Break brown blocks plugging old water sources with Rock Smash
• Place a Horsea Fountain (50 Coins from the PC Shop)
• Add decorative fountains and sprinklers

For a detailed guide, see How to Raise Humidity in Pokémon Pokopia.

Step 5: Set Up a Rain Dance Site

Follow Squirtle's guidance to set up a Rain Dance Site:

Item	How to Get
2 Castform Weather Charms (Rain Form)	1 from the shop, others in the cave
1 Plate of Food	Available at the shop
Leppa Berries	Found in trees throughout the area

Assign a Water specialty Pokémon to perform the Rain Dance.

Step 6: Trigger Rain and Free Onix

Once humidity is high enough:

1. Interact with Slowpoke to trigger its Yawn — rain begins
2. If rain stops, talk to Kyogre at the ocean to start a second round
3. Return to Onix's cave — the ground has softened
4. Use Rock Smash to break the clay bricks blocking Onix
5. You only need to break enough blocks — Onix handles the rest

Building Onix's Habitat

After the rescue, build a Smooth Tall Grass habitat for Onix:

1. Find the Smooth Rock — it's in the same cave where you freed Onix, on a grey block on the left wall before the path branches
2. Create Dry Tall Grass — use Leafage on unwatered dirt (this is the only way; it cannot be bought)
3. Arrange a 2×2 square of Dry Tall Grass and place the Smooth Rock next to it
4. The game confirms: *"Restored a Smooth Tall Grass habitat"*
5. Press the up directional button near Onix to guide it to its new home

Don't miss the Smooth Rock before leaving the cave — go back for it if you forgot.

Why Onix Is Essential

Onix's specialties make it one of the most valuable Pokémon in the Withered Wastelands:

Specialty	What It Does
Bulldoze	Required for rebuilding the Pokémon Center, operating Relocation Kits, and demolition tasks
Crush	Crushes fruits into paint for customization

Rebuilding the Pokémon Center

Onix is mandatory for the Pokémon Center rebuild. You need:

• Rebuilding Kit — 1,000 Life Coins from the PC Shop
• 8 Pokémon assistants with specific specialties (Onix must be one of them)
• Materials: Lumber ×20, Stone ×20, Leaf ×10, Vine Rope ×10

Quick Tips

1. Don't rush to the cave — Focus on raising humidity first; you can't free Onix without rain
2. Clear Slowpoke's entire path in advance — Water Gun every dry patch before escorting it
3. Grab the Smooth Rock from the cave — Don't leave without it or you'll have to go back
4. Dry Tall Grass needs Leafage on dry dirt — Don't waste time looking for it in shops
5. Leave space around the habitat — Onix is large and needs room to navigate to its home
