Snow Globe (enemy)
From the Super Mario Wiki
A Snow Globe is an enemy found in Wario: Master of Disguise. They appear in the Sneezemore Cave. The power of the Wishstone and a snowstorm created this species. It absorbs enemy attacks to grow even larger. Snow Globes act like Boos. When Wario is looking at them, they stand and when Wario is not looking at them they come closer. Snow Globes have a subspecies called Blow Globe. The water formed from defeating a Snow Globe allows Wario to raise Sipping Stalk.
The power of the Wishstone and a snowstorm created this monstrosity. It absorbs enemy attacks and uses that power to grow even larger.
