Big-O-Blaster

"B.O.B. this is. Big-O-Blaster built by Mingy and me. Life force from ground, plants and creatures it can suck."

- Blobbelda

The Big-O-Blaster (often shortened B.O.B.) is a powerful mechanical blaster built by Mingella and Blobbelda, located in Cauldron Keep. It is capable of sucking the life force of any living beings by blasting them with a laser beam, transforming its targets into lifeless zombies. This can also work in reverse, giving the life force stored in it back to someone.

Banjo-Tooie
In Banjo-Tooie, Mingella and Blobbelda intended to use the Big-O-Blaster to restore their sister Gruntilda's body, that became simply a skeleton after being buried under a boulder for two years by Banjo and Kazooie. Gruntilda first stole King Jingaling's life force in an attempt to restore her body, but it alone wasn't enough. After that, she decides to blast the entire Isle O' Hags as that would certainly absorb enough energy to complete her objective. However, in order to do that, the device needed a long charge-up. In this period of time, Banjo and Kazooie manage to arrive the tower where the weapon resided, defeating the witches and successfully restoring King Jingaling, his palace and Bottles, who was killed much earlier in the game.
