|First appearance||Mario's Time Machine (1993)|
The Bug Report is an item in the PC release of Mario's Time Machine. It is a list of this very game's glitches obtained as a physical item within the same game. Its icon depicts a close-up of a fly (a pun on "bug" referring to both an insect and a glitch). Mario obtains it from the game's unnamed quality assurance and tester after traveling in time to Novato in 1993 (1994 in the Deluxe re-release). After Mario gives the QA the Bug Fix he asked for, he thanks Mario and in return, asks him to deliver the Bug Report to the game's writers. After receiving it, Mario also marvels at how long the list is. Writer Andrew Iverson, meanwhile, tells Mario that he can only make the final rewrite of the game's script after he receives the latest bug report from QA. Mario promptly gives him the Bug Report, and Iverson promptly thanks Mario before getting to work writing Mario's final joke into the script.
