Shiny Diglett returns to Pokemon Go in April Earth Day event

Pokemon Go players can pick up an awesome new addition to their Pokemon collection when an upcoming Earth Day event debuts.

Niantic Labs is hosting a special Pokemon Go Earth Day event once more in April that will support environmental-based nonprofit organizations. In a partnership with Playmob, a gaming-for-food platform that works with other nonprofits and studios like Glu mobile, Miniclip, and Rovio, it will help bring fun to Pokemon Go players around the world while helping the environment as well.

Anyone who participates in the event will get awards for all Pokemon Go players – not just themselves. The more people who end up participating, the better the set of rewards will be. This year, rewards include new Ground-type Pokemon appearances as well as the coveted Shiny Diglett.

Here's how the rewards for helping to clean up the planet will shake out:

2,000 players: Increased appearances of Ground-type Pokémon
5,000 players: Shiny Diglett
7,000 players: Double Stardust and Candy for Event Spawns plus Groudon in Raids

This is just the first in a long line of Pokemon Go events where players have been able to pick up various new Pokemon and special forms of them. If you've been playing since the beginning, you'll no doubt remember special Pikachus with Santa hats and all other sorts of cool things for trainers to catch.

Last year's Pokemon Go Earth Day event found around 4,200 players participating, so there should be some decent rewards for all involved if that's any indication.
