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 everything just laying around, it springs up to have a go at any intruders. However, all they can do is run into their targets, and they have no health to speak of.

Weldar has the ability to spit out Wash-ups, Nuttas, and Boltoids. When spit, the parts run straight at the intruder without waiting for their personal bubble to be punctured.
