Bim promptly swears allegiance to them. On October 31, Bim's people invade Earth. The twins find their souvenir from HorrorLand maybe the only thing that can save or harm them! In the third part of the story, Meg returns to HorrorLand and is sent on a mysterious mission by Jonathan Chiller. Meg also spots another her running around.

The alternative cover art.

  • Bim's skin was originally green as seen in the full artwork. However, when the book was released, his skin was changed to orange. The book was later re-released with alternative cover art where Bim's skin is green, and his eyes were changed from purple to orange. A "SPECIAL EDITION" banner was also added underneath the Goosebumps HorrorLand logo.
  • With 192 pages and over 34,000 words, this is the longest Goosebumps book ever. The book Goosebumps Wanted: The Haunted Mask is 240 pages long, but it has a lower word count than Weirdo Halloween.
