Washup

Wash-up, Nutta, and Boltoid are a trio of large machinery parts (washer, nut, and bolt) that lie scattered around Grunty Industries. While they look harmless when inert, as with most objects just laying around the factory, they will spring up suddenly to attack any nearby intruders. However, they are relatively weak and can be easily dispatched.

Weldar has the ability to spit out Wash-ups, Nuttas, and Boltoids during the boss battle. When unleashed, the parts run straight at Banjo and Kazooie.
