Pokémon GO’s next Spotlight Hour will feature Elgyem on Thursday, Oct. 8, from 6 p.m. to 7 p.m. local time, giving Trainers increased chances to encounter the Psychic-type Pokémon and potentially find Shiny Elgyem. The event will also feature a 2× Catch Candy bonus, making the one-hour event an opportunity to stock up on Candy while hunting for Elgyem’s Shiny variant.
