Mumbo's Wrench

"Actually, you'll find that rusty stick to be a magical wrench with near-unlimited creative power."

- Lord of Games

Mumbo's Wrench is an item in the Banjo-Kazooie series, being the main tool of Banjo-Kazooie: Nuts & Bolts. It was given by the Lord of Games as a replacement for the previous moves Banjo and Kazooie had learned in the past, resembling Mumbo Jumbo's head.
