Bounce and Trounce

Bounce and Trounce is one of Mario's minigames in Super Mario 64 DS. It is also playable in New Super Mario Bros., where it is classified as a Variety minigame.

Gameplay
This game is very similar to Bounce and Pounce, but it is point-based rather than level-based. Three different Marios will fly up onscreen, and the player must make them fall on top of the Fly Guys. For every time a Mario lands on a Fly Guy, the player will get a point, and the Mario will bounce back up.

Tapping on a Mario will make him bounce up into the air approximately the same distance as one of the screens. Tapping his left side will make him fly up and to the right, and vice versa. If Mario should hit a Fly Guy from below, he will get stunned for approximately one second. After the Mario lands on a Fly Guy, more will come flying in from the side and a propeller sound will be heard. There can be up to six Fly Guys in the sky at the same time.

The level starts off with three big Fly Guys at the bottom of the Touch Screen while the Marios are thrown up from beneath the two screens. When the big Fly Guys are defeated, only regular-sized ones will appear in the Super Mario 64 DS version, while in the New Super Mario Bros. version, more big Fly Guys will appear, and after about ten of them are defeated, only regular-sized Fly Guys will appear. All Fly Guys fly around in different patterns and speeds, some in straight lines across the sky; others erratically jump around.

The player can drop three Marios off the screen before they lose.

Super Mario 64 DS
''Mario's surrounded by Fly Guys to trounce. Touch him on his left, right, or center to make him bounce in that direction.''

New Super Mario Bros.
''The sky is thick with Fly Guys! Help Mario stomp on their heads by tapping on him. Tap Mario on the left, right, or center to make him bounce left, right, or straight up into the air.''

Trivia

 * At the beginning of the minigame, the Mario to the right does not jump as high as the other two Marios and is the only one not to fly in a trajectory that hits one of the first three big Fly Guys.
