After you appear in a strange place, Professor Laventon asks you to help round up his runaway pokémon.
Save Your Game
You can press the up button on the directional pad to open your bag, where you can press A to save your game.
Check the Game Controls and Settings
In the save screen, you can press ZL or ZR to go to settings, where you can review the game controls and change your settings, such as text speed, camera controls, and so on.
Go to the Glowing Spot
You will see a glowing spot straight ahead. Go there and you will see a glowing, beeping object. Walk to it until it shows that you can press the A button to investigate. Press A and there will be a cutscene. You will receive the Arc Phone.
Find the Professor
Continue going along the path until you find the Professor. There will be a cutscene. You will get 50 Poké Balls.
Catch the Pokémon
A guide will appear on screen to teach you how to catch pokémon. Hold ZR while moving the Right Stick to aim, then let go of ZR to throw the Poké Ball. Or you can press B to cancel the throw. This guide will be added to your Survey Tips in the Settings section of your bag if you need to review it.
After you throw a Poké Ball at a pokémon, it will bounce, and if the pokémon is caught, the Poké Ball will shoot fireworks. (If you miss the pokémon, the Poké Ball that you threw will be lost.) After you catch your first pokémon, Professor Laventon will ask you to catch the other two, so do that now.
When you try to catch the third one, it will pop out of the Poké Ball. Professor Laventon explains that Poké Balls aren't guaranteed to catch the pokémon. Just try again until you catch it.
Afterward, there will be a cutscene and you will go to Jubilife Village.
