The Aurora Ticket, which was given out at a Nintendo Event, gives Pokemon Emerald, FireRed and LeafGreen players access to Birth Island. Nintendo Events are real life events, such as the Pokemon Rocks America in 2004, where players can download or gain access to Pokemon and game locations that are not accessible through normal gameplay.
Once players gain access to Birth Island, Pokemon Emerald players will encounter a level 30 Speed Deoxys. Before the player get to battle with Deoxys, however, he must first solve a problem upon setting foot on Birth Island. The puzzle consists of a moving triangle and the objective is to move towards it with the least number of steps.
