Mario & Luigi?!
From the Super Mario Wiki
Mario & Luigi?! is a level in Blubble Lake the Bowser Jr.'s Journey mode of Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.
Bowser Jr. and Kamek walk by Toad Town, where Bowser Jr. said he wanted to make a quick stop for evil scheming, although Kamek said there was no time despite normally being on board. Shortly afterwards, they spot Mario and Luigi, who were looking for the Star Cures. Bowser Jr. picked a fight with them, however Starlow reminded the Mario Bros. that there was no time for this, despite getting herself into an argument with Bowser Jr. right away. After Kamek told Bowser Jr. there was no time to be making new enemies, both sides then left for their respective tasks. Starlow however, did tell Bowser Jr. that Bowser was working very hard as well.
