Mario & Luigi?!
From the Super Mario Wiki, the Mario encyclopedia
Mario & Luigi?! is a level in Blubble Lake in the Bowser Jr.'s Journey mode of Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey.
This level has four battles, all of which have a Crawful as the first officer, as well as a Crawful captain in all but the last. Several Crawful troops throughout the level are under the effects of Malatone Formula:X.
After defeating the enemies, Bowser Jr. and Kamek walk by Toad Town, with Bowser Jr. wanting to make a quick stop for the purpose of evil scheming; Kamek, who is normally on board for such plotting, says there's no time for stops. Shortly after, they spot Mario and Luigi, who were looking for the Star Cures. Bowser Jr. tries to pick a fight with them, and ends up in an argument with Starlow, despite claiming that they didn't have time for this either. Following a bit of further arguing, during which Starlow explains to Bowser Jr. that his father is busy working hard as well, both groups leave to carry out their respective tasks.
