A Swirly Slab is a circular platform with a spiral on it in Wario World. If Wario performs a Wild Swing-Ding while standing on it, the Swirly Slab will rise, giving Wario access to higher areas otherwise inaccessible. Swirly Slabs first appear as metal disks in Horror Manner, and reappear in Beanstalk Way, where they are hidden within flower buds that must be Ground Pounded to be opened.
