Here are the new trainers looking for a Ghost and Flying thing in Pokemon in Brilliant Diamond and Shining Pearl that might be interested in tracking down the Drifloon. It is not easy and certainly worth it.
Players who want a Drifloon will surely need to make their way to the Valley just off the route. When you get here, Team Galactic will be up to no good and trying to take over the plant so they have an approach to the energy.
The great news is here that Drifloon will guarantee locations. The Friday after you get rid of Team Galactic, head off to the valley wind works and make sure to enter the building. Here you will find a Drifloon close to the sign.
You will get rid of all of them if you want to catch a Drifloon so make sure that you must defeat them in a fight. So on the global send-off, you will need to get off Team Galactic and then wait a week to try it.
