Boom Box

Banjo-Kazooie
In Banjo-Kazooie, Boom Boxes are found in Rusty Bucket Bay. If Banjo touches a Boom Box, it explodes on him, causing him to take damage. Kazooie make a Boom Box explode by firing an egg at it. Boom Boxes can also be safely defeated with Wonderwing. Boom Boxes explode after a few seconds of chasing Banjo and Kazooie.

Grunty's Revenge
In Grunty's Revenge, Boom Boxes appear in both Spiller's Harbor and Freezing Furnace. Boom Boxes act the same as in Banjo-Kazooie, although the variety of eggs allows for more ways that Kazooie can defeat them.
