Test Subject 042

Test Subject #042 is a Test Subject featured on a clipboard found in the Aperture Science Enrichment Center. #42 appears to be a chicken that failed the tests it took. It is unknown if these tests involved the Aperture Science Handheld Portal Device, as they are never mentioned elsewhere, and no dead chicken(s) can be found across the Enrichment Center.

Trivia
Finding the clipboard in Portal: Still Alive will unlock the "Tests Like Chicken" Achievement.
