Once completing task 1 of the Retro Pikachu event, a new Rumble area will be unlocked called "Yellow Forest".
The Yellow Forest can only be explored by Pichu, Satichu, Pikachu, Satochu, Raichu, Raitoshi, and Retro Pikachu
When sending out a Pokemon to the Yellow Forest, it will have the opportunity to find a Retro Egg, which will hatch out to be a Retro Pikachu. The Pokemon may also find Tiny Mushrooms, and berries. Pikachu's and Pichu's can also be recruited while your Pokemon is out on the mission. There is a higher chance to find a Shiny Picu/Pikachu via rumbling in the Yellow Forest.
