Blistering Buttons

Blistering Buttons is an area of Freezing Furnace's Grunty Industries in Banjo-Kazooie: Grunty's Revenge. It is a room containing 9 buttons, requiring Banjo to spell out "GRUNTILDA" with them by using either the Bill Drill or the Pack Whack, before he and Kazooie, due to the poisonous gas inside, run out of oxygen to make a Jiggy appear.
