The Rocket Boost is the second Staff Upgrade obtained by Fox McCloud in Star Fox Adventures. It gives Fox the ability to boost himself straight upwards with the Krystal's Staff to reach high ledges. Unfortunately, this can only be used in unison with Rocket Boost Pads, which are located on the ground in predetermined places around Sauria. This makes this ability much less versatile than many other Staff Upgrades. Like most Staff Upgrades, using the Rocket Boost also depletes Fox's Staff Energy Meter. The Meter can be refilled by collecting Staff Energy Gems, usually dropped by Magic Plants. Along with all other Staff Upgrades, it can also be assigned to the Y Button.
Fox obtains the Rocket Boost in the of the Ancient Well in ThornTail Hollow. He must plant a Bomb Spore into a Planting Patch, and then blow up the resulting Bomb Spore Plant in order to reveal the entrance to a cave, where the Rocket Boost is located.
