Rakk can be found flying around the highlighted area in Southern Raceway. About twenty rakk will spawn and all drop the oil sacs. A chubby rakk is often among them, and a badass can also spawn. Once a certain number of rakk have been killed and their sacs collected, Scooter will ECHO a request to bring the sacs to him instead.
