Avuncular

There's a popular mail order children's toy company called Wicked Uncle but the girls are fortunate to have one of their very own who supplies unusual and entertaining gifts such  paper butterflies that can be wound up with rubber bands and placed between the leaves of a book to give you a fright when opened; or, here, a printing set of different insects parts (wings, legs, antennae etc.) so you can create the kind of bugs that evolution never came up with.
