Dr. Maniac vs. Robby Schwartz is an entry in the Goosebumps HorrorLand sub-series, forming part of the meta-narrative arc. The story focuses on Robby Schwartz, a huge fan of comic books, who finds himself suddenly pulled into the terrifying, two-dimensional world of one of his favorite comics, where the villainous Dr. Maniac is real. Robby must survive the strange, panel-by-panel world of the comic book, which is designed to trap him. The plot combines the high-concept horror of being pulled into fiction with the ongoing meta-story of the sinister HorrorLand theme park, where all the unfortunate victims of R.L. Stine's stories are being trapped, forcing Robby to face his creation both inside and outside the comic panels.
