Arceus comes down and tries to hit you with a Dragon Meteor! Fortunately, your Shiny munchlax will be in the way and will get blasted instead! The shiny Muchlax's body will disintegrate, but you will get a Shiny Orb, which lets you make any Pokemon you want Shiny (1 use only)! Remembering the Stupid Ball you had, (Remember, you have it now, because you got rid of the Shiny Mew in a gruesome manner) you throw the Shiny Orb at Arceus! Use the Stupid Ball and you will have captured a Shiny Arceus!
