You are challenged to a balloon race in the Cobalt Coastlands.

The Request

Go to the Coastlands Camp in the Cobalt Coastlands and talk to the Balloon Race person to accept this request.

Balloon Race

Press B to dash as often as you can, to make sure you are going as quickly as possible. Press Y to jump through balloons that are floating. Beware of wild pokémon that may attack from the sides. You will automatically switch between Wyrdeer and Basculegion as you go over land and water. Keep in mind that while riding Basculegion, you can press Y twice to double jump.

Reward

After you pop at least 24 balloons in a single race, you get 1 Nugget and 10 Ultra Balls.
