The Rocket I is the first version out of 4 that the Proximity Mine Launcher, the Rocket Launcher, the Grenade Launcher, the Celebration (MKII), and the Snowman Cannon use for ammo.
This item can be found as a drop from Plantera along with the Grenade Launcher, or bought from the Cyborg NPC, which spawns after killing Plantera if you have a free house. Plantera can be found in Hard Mode after defeating every mechanical boss (The Twins, The Destroyer and Skeletron Prime), by destroying a Plantera's Bulb which emits a pink light in the Underground Jungle.
