GETTING SPIKED EAR PICHU

To get this rare Pichu, you need to get the Pikachu-Colored Pichu. Then, take it at the front of your party, with at least one space open in your party. Then, go to the shrine in Illex Forest. Once you get there, you should meet a special Pichu that will join your party. It is the Spikey-Eared Pichu. It cannot be evolved or traded, due to it being a special pichu, but it is explained in the game that it can't do those things because it has time traveled to much.
