Innerspace window

The innerspace window is a special type of window created by Handy and Papa Smurf as a medical examining tool in the EMPATH: The Luckiest Smurf story series. It is the Smurf version of an X-ray machine, except that it doesn't just show the skeletal framework of the Smurf, but also other internal organs. This was created before the Imaginarium, which eventually replaced the innerspace window by allowing a full model Smurf to be examined in a manner similar to a CAT scan. The innerspace window, however, is still being used by Dentist Smurf for his routine examinations.
