Spotlight Hour is an event in Pokémon GO that highlights a specific Pokémon for a one-hour period. During this hour, the featured Pokémon will appear more frequently in the wild, giving you an ample chance to catch them and stock up on candy.  

Here are a few tips for making the most of Spotlight Hour:

• Stock up on Poké Balls and other catching supplies. You'll be encountering a lot of the featured Pokémon, so you'll want to make sure you have enough Poké Balls, Berries and more to catch them all.
• Use Incense and Lure Modules. These items will attract more Pokémon to your location, which can be helpful for catching even more of the featured Pokémon.
