Super Smash Bros. Brawl/Home-Run Contest

In home-run contest you will see how far you are able to throw the sandbag. There are four differences from the home-run contest in SSBM:
 * 1) Now there's a shield surrounding the platform, so that only a hard hit will send the sandbag away (though the shield can be broken by multiple hits by attacks or simply the sandbag hitting it).
 * 2) Two players playing simultaneously.
 * 3) Two-player alternating game.
 * 4) Online competitions.

How to Play
After the game begins, attack the sandbag to get it's damage percentage up as high as you can in 10 seconds. Near the end of the 10, grab the bat, get next to it and do a Side Smash to send it flying. The camera will scroll to follow the sandbag's flight. Don't worry if it goes off the top of the screen. Once it hits the ground, it will bounce a few times and then skid across the ground before coming to a stop. Once it stops, it will show you, in feet or meters (depending on the language you're using for the game), how far you hit it. This is your score. After this, the game will prompt you to restart, go back, or watch a replay.

As a side note, the Smash Bros. Dojo states in their Home-Run records that a pair of Ganondorfs managed to launch the Sandbag over 15,000 feet, thus being the world record for co-op matches.
