How do you get Rotom on Pokemon Rumble?

In Pokémon Rumble, you can obtain Rotom by defeating it in the "Toy" form during specific stages. Look for it in the "Electric" themed areas, particularly around the later levels. Once you defeat Rotom, it may drop a toy version of itself, which you can then collect and use in battles. Make sure to check for any special events or updates that may affect its availability.
