Star 'Stache Smash
From the Super Mario Wiki
Star 'Stache Smash is a minigame featured in the Little Fungitown arcade during the events of Mario & Luigi: Superstar Saga and its 3DS remake, Mario & Luigi: Superstar Saga + Bowser's Minions. This minigame is mandatory for the story to progress, and the Mario Bros. can play this arcade game for free. The rules of Star 'Stache Smash, as explained by a Geno doll (an on-screen text bubble in the remake), is to tilt the tray with the items on it into the open Piranha Plant holes at each side of the screen. There is only one side open at a time. Pressing will tilt the tray to the right while pressing will tilt the tray to the left. Players have one minute (60 seconds) to rack up as many points as possible.
Every time the player gets an item through an open hole, a certain amount of points are awarded depending on the item. Mushrooms are worth one point, Fire Flowers are worth three and Stars are worth five. Bob-ombs are also worth one point, but they also cause the other side to open and close the side they landed in. In the story, the Mario Bros. win an Invincishroom (a Poison Mushroom that is mistakenly called an Invincibility Mushroom in the remake) for getting a score of 200 or better. This causes Mario to gain Bean Fever after consuming the Invincishroom.
Star 'Stache Smash can be played later in exchange for Hee Beans. The chart below lists the amount of points required to earn a certain amount of Hee Beans.
