Wingnut-Grumpy's Assistant who was formerly owned by Grizzle. Wingnut was Grizzle's excitable little robot assistant. Grizzle built Wingnut out of scrap metal and hardware. Wingnut is a nice well-meaning robot who is terrified of Grizzle, and Grizzle is very mean to him. But on his own, Wingnut is nice to everyone. He can be very helpful too. He has strong robotic arms, can motor around very quickly on his single tire, and he can even spin his wingnut cap and fly like a helicopter. His belly panel can even pop open and he can project holograms.
