For this special event, you must complete the sidequests all the way up to the end of Sinnoh, once you have done this, you will have the option to exchange all of your Sidequest ribbons and progress for a Splash plate. Use this Splash Plate to transform your regular Arceus into an Arceus (Water). You can change the form of any variant of your Arceus such as Normal, Shiny, Dark, Mystic, Metallic and Shadow. Each Splash Plate only has one use, so use it sparingly - To get another, you must complete Sidequests right back to the end of Sinnoh again to exchange the Ribbons for a Splash plate.
