Collecting Pokémon is a crucial aspect of the Pokémon franchise. Some of the game's collectible monsters take a mysterious approach to collection, including Phione, one of the game's Mythical Pokémon.
Players can get Phione by placing Manaphy in the Solaceon Town Nursery with a Ditto. After some time has passed, the two Pokémon will create an egg, and after it's hatched, they'll get Phione. Manaphy is a Mystery Gift available to all Brilliant Diamond and Shining Pearl players until Feb. 21, 2022.
To claim a Mystery Gift, players must first complete the first gym and go to the TV Station in Jubilife City. After talking to an attendant there, the Mystery Gift option will be available for players to use in the game's pause menu (press X to open the pause menu.) Reaching the Jubilife City TV Station happens as part of the story, so continue playing normally if you still don't have access to the Mystery Gift option.
Ditto can be found in the Grand Underground's Dazzling Caves or Route 218. For more information on finding Ditto, check out the video below for an in-depth breakdown.
