Participating in Pokémon GO Community Day events is always a thrilling experience, especially when hunting for shiny Pokémon like Lechonk. From my experience, using a combination of Razz Berries, Golden Razz Berries, Pinap Berries, and Silver Pinap Berries can significantly increase the catch rate and sometimes even the number of candies you receive, which is vital for evolving and powering up your Pokémon. During the event, stocking up on different berries before heading out is crucial. For example, Razz Berries help calm the Pokémon to make catching easier, while Pinap Berries double the candy you receive from a successful catch. Golden Razz Berries offer the highest catch rate boost, making them invaluable for rarer or higher CP shiny Lechonks. When it comes to Poké Balls, I tend to start with Great Balls for regular Lechonks but switch to Ultra Balls for those with higher CP (such as 192, 233, or 344 CP) to increase the likelihood of a successful capture. Holding your device steady and timing curveballs correctly also improves your chances. I also recommend paying attention to weather conditions since they can affect spawn rates and CP levels. Sunny weather, for example, might increase the likelihood of encountering higher CP Lechonks. Finally, don't forget to participate fully in the event's bonuses, as they might include increased spawn rates or experience points, making your grinding more rewarding. Collecting and managing your inventory of berries and balls before and during the event ensures you won't run out when it counts. Enjoy the hunt and good luck catching that shiny Lechonk!
