The Incredible Shrinking Fifth Grader was alleged to be the twenty-sixth book in the Goosebumps Series 2000 book series. But it was later cancelled, because R.L. Stine's contract with Scholastic expired. Contrary to belief, it was not being planned as a book in the cancelled Goosebumps Gold book series. Unlike the Goosebumps Gold books, however, neither a story nor a cover for The Incredible Shrinking Fifth Grader were ever released. It is possible that some plot ideas were recycled for Goosebumps Hall of Horrors Book 2: Night of the Giant Everything but nothing has been said.
