Drill Seargant Jamjars is Bottles' brother and replacement trainer for Banjo and Kazooie in Banjo-Tooie. When Banjo and Kazooie first meet him, he comes out of his hatch and says "Drill Seargant Jamjars, reporting f'duty, sir". The only way to learn a move is if you have a certain amount of musical notes. Otherwise, Jamjars will tell you to go collect them if you don't have them. Jamjars' hatch will have a red light on it if you haven't learned that move yet. And when you learn it, the light will turn green. Jamjars puts his lesson into a rhyming song while you're learning the move. When Jamjars is finished teaching you, he will say "Dissmissed!" and jump back into his hatch. Occasionally, there will be a gag that makes his hatch lid close before he jumps in, causing him to hit his head. Banjo and Kazooie must go looking around the worlds looking for each hatch. There will be 1-3 hatches in each world.
