Crystal Prep Shadowbolt Sour Sweet was there when everything went down during the Friendship Games, and even helped save people from falling through the rips into the strange world of Equestria.

A Manehattan couple answered a letter in the post asking for assistance with people from the other world, hoping to help the community.

They'll need all their friends to help.
