Drill Sergeant Jamjars is Bottles' brother and serves as the replacement trainer for Banjo and Kazooie in Banjo-Tooie. Assertive and strict, this militaristic drill sergeant mole requires the pair to prove themselves by collecting a certain number of musical notes before teaching them any new moves. Like his brother, Jamjars doesn't think too kindly of Banjo's smart-aleck sidekick, Kazooie, but tolerates her enough to teach the pair some of the game's most important moves, possibly because of Kazooie's enthusiasm to beat the living (or in this case, undead) daylight out of Grunty.
