A new story added in Mario & Luigi: Bowser's Inside Story + Bowser's Journey. This new addition to the main story sees Bowser Jr. as the titular character. While Bowser is occupied during the main story, this story sees Bowser Jr. on an adventure to cure the blorbs himself after it causes numerous minions to balloon up to an immobile state.
Different from its predecessor (Minion Quest: The Search for Bowser, included in Mario & Luigi: Superstar Saga + Bowser's Minions), it doesn't need to be accessed from within Bowser's Inside Story.
