Fury Sun
The Fury Sun is an object that appears in the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury. It sits in the middle of Lake Lapcat and takes the form of a spiky blob of goo that resembles Bowser's Spike Ball form in Mario & Luigi: Bowser's Inside Story and the Super Mario Galaxy games, as well as the spiky shells he throws in his Super Mario Odyssey battles, in which Fury Bowser sleeps.
The Fury Sun slowly rises from the ground, spinning rapidly before quickly launching into the air to signify Fury Bowser becoming active. This usually happens at intervals of roughly six minutes, but scanning any Bowser amiibo in the game causes him to appear instantly.[1] After a while, or if the player collects a Cat Shine, Fury Bowser stops attacking and retreats back into the Fury Sun.
