Big O Blaster

Gruntilda the Witch's B.O.B.
The Big O Blaster, also known as B.O.B., was built by Mingella and Blobbelda to make Undead Grunty alive again. It only has two buttons, SUCK and BLOW. Once Mingella and Blobbelda have brought Gruntilda the Witch back to their new lair at Cauldron Keep, Grunty uses the Big O Blaster's SUCK function on King Jingaling. Luckily, they missed Banjo and Kazooie. If they had gotten to Cauldron Keep 5 minutes earlier, the duo would have been zombifyed like Jingaling was.

***SPOILER ALERT*** B.O.B.'s BLOW Function
After Banjo and Kazooie survive Gruntilda the Witch's Tower of Tragedy Quiz, they enter the Gun Chamber on the way to the roof and find the Big O Blaster. The duo hits random buttons until the life force gained from draining King Jingaling is shot right into Zombie Jingaling and he is brought back to life. They somehow also find enough extra life force to bring Bottles the Mole back to life, even though he wasn't drained by the Big o Blaster. Where this extra life force came from is a mystery.
