Mumbo's Wrench

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

- Lord of Games, Banjo-Kazooie: Nuts & Bolts

Mumbo's Wrench is the main combat tool used in Banjo-Kazooie: Nuts & Bolts. It was given to Kazooie by L.O.G. once the duo reached Showdown Town and has a resemblance of Mumbo Jumbo's head.

Mumbo's Wrench can be used to attack in the air and on the ground to help Banjo defend himself on-foot because of the loss of almost all his abilities. When used in the air, it can help propel Banjo forward, too. Aside from being used in combat, it can also be used to levitate many objects. It can also be used to activate Wrench-It Bolts, which can dispense Jiggies, release Jinjos, open gates, etc. The Wrench is also used to create and modify the vehicles in Mumbo's Motors and inside of the worlds, and repair any broken pieces of the vehicle.

Mumbo's Wrench later reappears in the Xbox 360 version of Sonic & Sega All-Stars Racing. Every characters in this game has an "All-Star" move, with Banjo and Kazooie's All-Star move being the "Jiggy Rain". This move consists of Kazooie using Mumbo's Wrench to summon huge Jiggies to rain down the track, blocking and spinning out the other racers. The music used during this All-Star move is a remixed version of the Wonderwing theme.
