Arcturan (Goosebumps)

The Arcturans are a race of aliens and one of the main antagonists that appeared in the climax of the twenty-third Give Yourself Goosebumps book, Zapped in Space.

Appearance
Arcturans are described as big bald heads that bare resemblance to a human's, but having the stark contrast of pale blue skin. They're kept inside three small, round glass cases and explain their peculiar state to the unnerved reader by saying Arcturans had outgrown the use of bodies as more of their time was spent thinking.
