Chuffy

Chuffy is a Train that was used in Banjo-Tooie and is operated by Old King Coal. It was originally found in Glitter Gulch Mine; however, Chuffy had fallen off its tracks, so Mumbo Jumbo was needed to use the Mumbo Pad in front of the fallen train to put it back on the tracks. Afterward, Banjo and Kazooie entered the train and attempted to use it, but the train's owner, Old King Coal stated that they would have to fight him first to use his train. A boss battle inside the boiler ensues, and once the duo claim victory, they are free to use Chuffy as they like.

To use Chuffy, Banjo and Kazooie must open stations in each world by activating a Train Switch. Not all worlds have a train station though. Once activated, they need only to stand in front of the information sign by each station to have Old King Coal bring Chuffy to the station. Banjo and Kazooie use Chuffy quite a bit to transport different characters, obtain certain Jiggies, and travel quickly between worlds. Chuffy was used to sneak into Grunty Industries as the entrance was locked from the outside.

Hailfire Peaks is a unique world in that it has two train stations for use on the Lava Side and Icy Side, respectively. However, Chuffy is not able to travel to the Icy Side of Hailfire Peaks until his boiler is cooled, as the drastic change in temperature would damage Chuffy's engine. This requires Banjo and Kazooie to bring the train to the Lava Side station and find a way to cool Chuffy's boiler, which can be done by climbing up to a platform above the train and using the Beak Buster ability on the camel Gobi's hump to pour water into Chuffy's boiler.

Trivia

 * In the XBLA version of Banjo-Tooie, you can check under "Help & Options" on the pause menu for Jiggy Tips, which gives you a hint for each of the world's Jiggies. If you open this menu while inside Chuffy, the menu will display Glitter Gulch Mine's Jiggy Tips, regardless of what world Chuffy happens to currently be in.
