Broque Madame's Handiwork
From the Super Mario Wiki
Broque Madame's Handiwork is a level in Blubble Lake in the Bowser Jr.'s Journey mode of Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. It features the first battle with Broque Madame.
After obtaining the ingredients for Skeletone Formula:D, Bowser Jr., Kamek and Morton visit Broque Madame and ask her to make the Skeletone. However, Broque Madame asks for a massage first. She starts the battle alone, however she can use Call for Backup to summon several Scutlets. After doing this, she creates the Skeletone for Bowser Jr., only to have it stolen by Kaley and Dieter, who turn it into Malatone Formula:X using a Malodorous Fibbian's breath.
