Find the Jetpack is a mission in Ratchet & Clank, taking place in the Blarg Research Outpost on planet Gaspar. After Ratchet and Clank obtained the Grindboots in the Depot, they were able to explore the planet further searching for their original goal, the XK-81 Jetpack, that could be used for the Galactic Rangers. The two along the way encountered the Brain Scientist, a non-hostile blarg in possession of a Jetpack, willing to provide it in exchange for telepathopus brains.
