The Bottle rocket is an item in EarthBound Beginnings and EarthBound. In both games, it is limited to use only by Lloyd and Jeff Andonuts, respectively. In Mother, the Bottle Rocket deals 20 fire damage to all the enemies' hit points. In EarthBound, it only deals 90-150 damage concentrated to one enemy, and has a chance to miss based on Jeff's speed compared to the enemy's speed. It's more likely to miss than PSI Rockin as well, so equipping Jeff with the Rabbit's Foot can make it more likely to get heavier damage with Big bottle rockets and Multi-bottle rockets. Jeff also uses bottle rockets to attack during his assist trophy appearances in Super Smash Bros. Brawl.
Big bottle rockets are essentially 5 Bottle rockets, Multi-bottle rockets are 20.
