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.
Players must ground-pound an inflatable blue Thwomp enough to completely deflate it. The higher the jump before the Ground Pound, the more air that gets deflated. The first team to completely deflate its Thwomp wins. If neither team has completely deflated their Thwomp within 30 seconds, the game ends in a tie.
