Boss Boom Box

Boss Boom Box is a large Boom Box who resides in a large compartment of The Rusty Bucket in Banjo-Kazooie. He is the boss of Rusty Bucket Bay.

To access Boss Boom Box's room, a large box of TNT must be dropped off the stern-side crane in Rusty Bucket Bay, which explodes and destroys a large set of doors in the floor. Banjo and Kazooie can then enter the room below to find Boss Boom Box, who leaps up from the floor once approached and hops around. Despite being a large Boom Box, Boss Boom Box contains no explosives, so touching him only causes damage. Once hit a certain number of times, Boss Boom Box splits into two smaller boxes. This continues, with each box having less health and more speed, through four box sizes. Once all eight normal-sized Boom Boxes (that don't explode) are destroyed, the last one drops the Jiggy. Boss Boom Box does express much desire for the Jiggy. A total of 15 boxes are destroyed in the battle.

Boss Boom Box appears as one of the Timed Challenges in Grunty's Furnace Fun. Banjo and Kazooie are given seventy seconds in which to beat him once more.

Rolling into Boss Boom Box is an effective way to damage it, but firing eggs at a rapid pace also works well, provided the player has enough of them.

Trivia

 * There is a glitch used by speed-runners to get Boss Boom Box's Jiggy without having to fight him (since even using the Wonderwing, which destroys each box in one hit, still takes a bit of time). If Boss Boom Box is hit by a Blue Egg while still laying on the ground, he will forget to grab the Jiggy when he gets up. It is then simple enough to grab the Jiggy and leave the room (since the room is not sealed for the battle).
 * Boss Boom Box is the only boss that doesn't remix the level's main theme, as instead, a remix of the music used for the inside of the Rusty Bucket and the Engine Room is used instead.
