Ug The Caveman

Ug the Caveman is a minor character from the Luigi's Mansion franchise. He makes his debut in the third game, Luigi's Mansion 3. Ug holds the portrait of a captured Mushroom Retainer and the Basement 2 elevator button in his possession.

Physical Appearance
During his battle's first phase, Ug comes out as a Tyrannosaurus's undead skeleton. His second form is that of a caveman, hence his name.

Battle
The battle begins when Luigi makes his way the hotel's Unnatural History Museum, which is located on the ninth floor, spotting a trapped Mushroom Retainer's portrait. During his battle introduction, Ug, as the undead Tyrannosaurus Rex skeleton, eats the portrait and threatens Luigi.

Luigi has to use the Poltergust G-00 to launch egg fossils at Ug's bony body to expose his chest, then strike the undead dinosaur's chest. There are three eggs during the first round, and only two will be consumed right after this time. Doing this right triggers the second phase.

The second phase is the same, but Gooigi must sacrifice himself to the bite. In this way, he lets his solid counterpart launch the third egg at Ug's chest. This causes Ug to get angry, bringing him to phase three.

During the third phase, Ug is more mobile. Luigi needs good timing to toss the fossil parts at Ug to break him apart, initiating the fourth and final phase.
