From the Super Mario Wiki
Nabeatsu Toieba (ナベアツといえば, lit. "Speaking of Nabeatsu") is one of the six microgames made by Sekai no Nabeatsu with WarioWare: D.I.Y. for download in the category Big Name Games. It was available in Japan from April 29 to July 10, 2009.
A stylized Nabeatsu is seen counting, as shown by speech bubbles with numbers in them. When Nabeatsu has counted to three, the player has to tap the respective speech bubble in order to win the game, causing Nabeatsu to make a grimace. The game is a reference to the comedian's common performance: Counting aloud and acting crazy whenever he says a number that is a multiple of three or contains a three.
