At a beach, an inflatable Thwomp falls onto the ground, and the camera zooms out revealing a second inflatable Thwomp as the teams land on each respective one. In Mario Party: The Top 100, the Thwomps have their modern facial expression instead.
Players must Ground Pound an inflatable, blue Thwomp made of rubber enough to completely deflate it. The higher the jump before the Ground Pound, the more air gets deflated. The first team to completely deflate their Thwomp wins.
The Mario Party: The Top 100 version of this minigame is the first time any Thwomp has been portrayed as something resembling their blue cubic appearance since Super Smash Bros. Brawl, released nine years prior.
