A Klang is an enemy in Grunty Industries which disguises itself as an oil drum to fool intruders. Their disguises, however, are less than perfect since they stay somewhat distanced from actual barrels. A Klang will spring to life when Banjo and Kazooie get near it and will attack by trying to bump the bear and bird. If a Klang has a Toxi-Gag inside of it, it is considered a Toxi-Klang. It is also condisidered a Toxi-Klang when it has toxic waste dripping out from its lid.
