When the Banjo-Kazooie main series came back after an absence since the release of Grunty's Revenge, this game has a new storyline and plot due to the vehicles. For the vehicles, the weapons as well as the chameleon vehicle part are one of the best parts of the game. The sole problem is on the Terrarium of Terror act 5, one challenge for the horn, "Unpleasant Fat Oaf" is when Grunty disappears to the surroundings with the aid of the chameleon, all of the sudden, a MASSIVE blast of air along with a sound that seems abnormal to the horn is fired to blow Banjo's vehicle away. This had gave me the inspiration to fire the same blast of air. I do not know if it is caused by the horn or a vehicle part in Grunty's UFO. Anyway, this game is the best. Strongly recommended.
