The Incredible Shrinking Fifth Grader was going to be the twenty-sixth book in the Goosebumps Series 2000 book series. It was never released, due to R.L. Stine's contract with Scholastic expiring. The plot to the book is unknown.
Tim Jacobus, the cover artist for Goosebumps Series 2000, said he did indeed create cover art for the book. Jacobus says the illustration featured a tiny sized kid holding a giant pencil, warding off a white rat on a desk in a classroom. According to Jacobus, the artwork was finished. However, Scholastic called Jacbous and told him not to turn it in. They also said it would be his last Goosebumps cover.
- It is possible that some plot ideas were recycled for the second Goosebumps Hall of Horrors book, Night of the Giant Everything, but nothing has been said.
