Luiginary Stache Tree
From the Super Mario Wiki
The Luiginary Stache Tree is the first Luiginary Work seen in Mario & Luigi: Dream Team. It is a stationary work that allows Dreamy Luigi to pick up Mario with his mustache and throw him to previously inaccessible places. It is activated and used by Starlow by grabbing and letting go of Luigi's mustache on the touch screen. This is also the Luiginary work where Prince Dreambert explains how to use Luiginary Works.
