You’ve met the teenage versions of Fox Mulder and Dana Scully, but now get ready for the child versions of the iconic duo.

Kim Smith’s upcoming picture book, The X-Files: Earth Children Are Weird, sees the best pals go camping in a backyard during an overnight sleepover — complete with a fancy tent. Only, the night doesn’t go as planned as young Mulder and Scully encounter all sorts of strange lights and sounds. And as the exclusive excerpts below show, both characters react in classic fashion: Mulder attributes the strangeness to aliens, and Scully searches for a rational explanation… if there is one.
