The Fūsen Block is a rare, large block found in Mario & Wario. Unlike other blocks, Wanda has no control over them, as they deflate and inflate periodically. Sometimes, Fūsen Blocks in the area all work in tandem, and at other times, they perform opposite nearby ones. Wanda can only interact with her character to make sure they properly traverse these platforms. They are most prominent in LEVEL 7, where they appear in nearly every area.
