Maximum Friendship Glitch: This glitch is done by using the potion you receive from the PC on a fully healed Pikachu. The item will have no effect, but will continue to raise Pikachu's Happiness for each use.
Pikachu Off-Screen Glitch: This glitch allows for the Pikachu Sprite Icon to disappear off the screen, but a Items Glitch or Glitch City must be used to do so.
