Gruntbot

"My Gruntbots are out there causing trouble, smashing those cretinous worlds to rubble!"

- Gruntilda Gruntbots are the main enemies in Banjo-Kazooie: Nuts & Bolts. As their name suggests, they serve as Gruntilda's minions, being built by her in order to make Banjo and Kazooie's quest harder. There are many different types of Gruntbots, each with unique appearances and properties. They come in many different sizes, and can be defeated by getting shot with projectiles and being hit by either Mumbo's Wrench or the duo's vehicle.

It is unknown what their role and attacks would've been, and most information about them is simply speculation based off on their names and appearance. Tombstones with their names and concept art can be found in the Mad Monster Mansion exhibit of Banjoland.
