From the Super Mario Wiki
Sandbag also makes three appearances in Super Smash Bros. Brawl. In the Wi-Fi connection mode, as players are waiting for the game to load, or other players to connect, they are able to attack Sandbag on the waiting screen. It will also appear in the Home-Run Contest mode of the game, once again. It also appears as a container, but can "lose" several items unlike other containers.
