How to find Onix in Pokémon Pokopia

Onix is a Bulldoze Pokémon required to progress the main storyline in the Withered Wasteland. Bulldoze Pokémon can remove debris, which you need to start rebuilding the first Pokémon Center; none of the initial creatures can help, but deep inside the caves you will find Onix.

From the destroyed Pokémon Center, go west following the path of red bricks. Break through the wall under the bridge with Rock Smash to reach the shore, then head north into the rocky area until you see a green gate. Before the gate, on its east side, an opening leads into a cave; inside you will hear someone asking for help. Break down the brown rocky wall (the same kind you broke under the bridge) and you will see Onix through a small opening.

The rocks trapping Onix are too hard for Ditto and even Onix to break. To free it, talk to Professor Tangrowth and begin the "Yawn up a Storm!" request to raise the area's humidity and make it rain.
