A Sleepy Bomb is an item that appears in Super Mario RPG: Legend of the Seven Stars.
When a Sleepy Bomb is used, it will put all enemies on the screen to Sleep. However, this item does not work on bosses or larger enemies (or those immune to status effects such as Sleep). Sleepy Bombs can be purchased at the shop on Tadpole Pond for one Frog Coin. They may also be dropped by certain enemies.
