Capsule Spawn

Item Pick is 's standard special move in Super Smash Flash 2. Sandbag picks a random item from inside himself, in the form of a capsule. After throwing the capsule it will open and dispense an item for Sandbag to use. However, the items are always used for offense, never for healing. If items are turned off, the Capsule will not dispense any items.

The capsule by itself, though able to explode and effective when it does, is not very damaging when non-explosive, and the startup time is slow – enough to recycle the startup sound effect from Falcon's Crest. This is not to mention that the capsule can easily be caught and thrown back. So while potentially overwhelming in casual play due to the game-changing status of items, its use in competitive play is limited at best and actively harmful to the user at worst.

Origin
In Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U, Sandbag appears as a standard item himself during play. When attacked heavily, he will drop any other item repeatedly until he disappears. Bomb Throw references the same property.
