Pokémon Brilliant Diamond and Shining Pearl have an expansive roster of Pokémon to choose from, and while many are easily obtained, some can be harder to find. One Pokémon that is hard to find is Rotom. Rotom also features many different forms it can take.

Rotom is an electric and ghost-type Pokémon, the only one typing. You will first need Rotom and head to theGalactic Building in Eterna City.There is asecret room on the first floorof this building. You cannot do this until you complete the Sinnoh Pokédex. Here you’re able to find appliances that you can add to your catalog and change Rotom’s form.

You can catch Rotom after Seeing all Pokémon in the Sinnoh Pokédex—you do not have to catch them. Speak to Rowan, who will upgrade your Pokédex. Head to the Old Chateau and then go to the room on the second floor with the TV. Interact with it, catch Rotom, and grab the key in the same room.

Take this to the Galactic Building in Eterna City. On the left side of the bottom floor is a secret room. Enter this with the key, and you will see five appliances. Interact with them to add them to your catalog and change Rotom’s form.
