They're made of garden gloves and do not speak. Instead, they communicate with the lights from their eyes. They're first encountered in the Library so I've made a book to use as a stand. As seen in the photos, you can add LEDs to the eyes. Wires can be run down through the neck and into a cavity in the chest, that can hold small batteries. If you don't want to add lights you can just use the alternative face plate (without holes). The finished character measures around 160 mm tall. The book measure 160, 117, 14 mm.
