|Behind the Scenes|
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.
In Zapped in Space, the Arcturans are big pale blue human-like heads kept inside small round glass cases. The book's cover, meanwhile, depicts them as green two-headed humanoids with multiple arms.
In Goosebumps 2: Haunted Halloween, the Arcturans resemble the Greys yet wear a futuristic robe in multiple shades of grey with light blue orbs around the collar.
