August has arrived, and with it comes a new set of Field Research tasks to complete in Pokemon Go. As Niantic previously revealed, this month's selection of challenges revolve around Electric-type Pokemon and ultimately lead to another encounter with Raikou, but that isn't the only rare Pokemon players can acquire through the quests.

Along with the Field Research tasks, Niantic has introduced a new Pokemon to the game: Spinda. The Spot Panda Pokemon originally debuted in the series' third-generation installments, Pokemon Ruby and Sapphire, and is notable for having more than four billion possible fur patterns. However, it was one of the small handful of monsters who were skipped over when Niantic began introducing Gen 3 Pokemon to Go, making this the first chance players have to add one to their collection.
