Super Mario Bros. (Stomp)
From the Super Mario Wiki
Super Mario Bros. is a microgame found in WarioWare: Touched! in the Retro Action stage. It is set in the NES game of the same name. There is another microgame in Touched! based on Super Mario Bros. under the same name: Super Mario Bros..
The objective is to tap the on-screen enemies to defeat them. Enemies such as Koopa Troopas and Buzzy Beetles need to be tapped once to make them hide in their shells, and once more to make them slide across the ground, just like in the games. This move can be used to defeat other enemies like Spiny, which are the only enemies in the microgame that cannot be defeated by tapping them. This microgame has twice the time to complete than the others (8 seconds), as it takes time to remove the enemies from the screen.
This microgame is won if all the enemies are removed from the screen. In the Grid, the player needs to score 25 points to pass this microgame.
Mario will also pop up when the microgame is cleared. On level 1, he's small and riding on a cloud. Level 2 has Super Mario on a cloud. Level 3 has Mario being even bigger, and riding on a Bullet Bill.
