After you make your way through Route 4, you arrive in Paniola Town and visit the nearby Paniola Ranch.

Paniola Town

As you go into town, Hau will challenge you to a battle, healing your pokémon first. Hau has a level level 16 starter that can use a Z-Power (Dartrix if you chose Litten, Brionne if you chose Rowlet, or Torracat if you chose Popplio), a level 15 Pikachu, a level 14 Noibat, and a level 14 Eevee. You get 560 Pokédollars for winning.

Afterward, Hau gives you a Dire Hit.

Go into the house to the left of the Pokémon Center and go to the back, and go up the stairs. Talk to the Magmar in the bottom-right corner to get a Quick Ball.

To the left of this house, talk to the Miltank to get a free Moomoo Milk. You can get one free Moomoo Milk from them each day.

To the left of the Miltank and the man, there is a wagon full of hay. Check on it to get a Revive.

Next to the Pokémon Center, there is a man who will buy different types of Poké Balls from you for a lot of money.

In the bottom-left part of town, some Team Skull Grunts are trying to steal a Bottle Cap from a Vulpix. Talk to them to battle. Team Skull Grunt has a level 14 Rattata. You get 448 Pokédollars for winning.

After the battle, the Grunts leave, the Vulpix runs away, and the woman asks you to come back tomorrow.

Go north from Paniola Town to reach Paniola Ranch.

Paniola Ranch

Go up the path and talk to the woman in the green dress to battle Madame Elizabeth. She has a level 15 Carbink. You get 3000 Pokédollars for winning.

Go farther through the ranch and the Pokémon Breeder up ahead will talk to you. You will meet Captain Mallow, who adds Stoutland to your Ride Pager. Stoutland's special ability is to search for hidden items. Press B while riding Stoutland to search the area for hidden items.

Mallow says to go through Route 5 to reach Brooklet Hill and meet Lana.

While riding Stoutland, if you hold B and there is a blue exclamation mark over your head, there is a hidden item nearby. Move around holding B until the blue exclamation mark becomes a red one. When you see a red exclamation mark over your head, press A to get the hidden item.

There is a hidden Repel if you go downward from the Pokémon Breeder you talked to earlier, and there is a hidden Moomoo Milk above the Miltank pokémon that brought you to Mallow earlier. There is a hidden Fresh Water above the Tauros on the left side of the area, next to the pond.

Check on the Tauros at the upper left of the Miltank Paddock and you will be asked to battle the Tauros. Pokémon Breeder Wesley's Tauros is level 15. You get 600 Pokédollars for winning. Afterward, Wesley gives you a Scope Lens.

Talk to a girl near the upper-right corner of the Miltank Paddock to get 5 Adrenaline Orbs.

When you exit the Miltank Paddock area, you can go south to find some tall grass. Use Stoutland to find a hidden Soda Pop to the right.

There is a ramp to the left, and there is a hidden Super Repel below it.

Southwest of the ramp, there is an Ether.

You can battle Pokémon Breeder Glenn on the ramp. He has a level 15 Mudbray. You get 600 Pokédollars for winning.

Go to the southeast part of the area, over a ramp, and go north to find the Pokémon Nursery. Talk to the Miltank there to heal up your pokémon.

Go south from that Miltank and enter the fenced area. There is a hidden X Sp. Def there.

Pokémon Nursery

In the Pokémon Nursery, you can give two pokémon to the girl behind the counter. If the pokémon are compatible, they might lay an egg. The girl outside of the Nursery will tell you if your pokémon have laid an egg.

The Pokémon Nursery is different from Pokémon Day Care in other regions. The Nursery here in Alola won't level up your pokémon or make them learn moves.

Talk to the girl in the upper-left to get TM10 Hidden Power. You can talk to this girl to find out what type a pokémon's Hidden Power will be.

Back Outside

To the right of the Nursery, there is a red truck, and behind it there is an Amulet Coin. If a pokémon holds it and participates in battle, you will earn twice as much money from the battle.

You can battle the Rising Star who is doing situps under the truck. He is Rising Star Micah. He has a level 15 Lillipup and a level 16 Magnemite. You get 768 Pokédollars for winning.

In the grass south of Micah, there is a hidden Big Mushroom. South of that, you can find a Heal Ball.

Go north from here and you can talk to the man to battle Gentleman Gerald. He has a level 15 Sableye. He is weak to Fairy attacks, and is immune to Normal, Fighting, and Psychic attacks. You get 3000 Pokédollars for winning.

North of Gerald, go to the fence on the left side to find a Poké Finder spot, where you can take photos.

Keep going north to reach Route 5.
