Gong

Gongs are objects in Super Mario 3D World and Super Mario 3D World + Bowser's Fury, appearing only in Hands-On Hall and Back to Hands-On Hall. They can be activated by rolling into them, using a Boomerang Flower to throw a boomerang at them, using a cat swipe or tail whip, or using the touchscreen or touch cursor. Each gong has two ropes holding it and has Bowser's emblem in the middle.

Locations
There are four gongs in Hands-On Hall and five in Back to Hands-On Hall, for a total of nine gongs.
