Main Studio Blue Key Challenge is a side Quest in Mario + Rabbids Sparks of Hope, exclusively in the Rayman in the Phantom Show DLC. It is found in the Main TV Studio at the Space Opera Network.
In this Quest, the heroes must find a Blue Key Ring, and then pass through it. After doing so, the heroes only have a short time to collect all eight of the Blue Key pieces. After collecting them all, a treasure chest containing coins will appear. The quest is then complete, and the heroes are awarded a Planet Coin.
