Pokémon Go is hosting a Sustainability Week event to celebrate Earth Day from April 20-25.

During the event, Pokémon like Psyduck, Sunkern, Drilbur, and Ferroseed will have increased spawn rates. Binacle and its evolved form, Barbacle, will also be appearing for the first time. Trubbish and Garbodor are both also making their Shiny debuts in Pokémon Go.
