List of Mario educational games
The popularity of the "Super Mario" series led to the release of several spin-off "Mario" educational games from 1988 to 1996. Nintendo had little involvement in the development of these games; they were created by various other developers, including The Software Toolworks and Interplay Entertainment. Some of the titles were released exclusively for either the Nintendo Entertainment System (NES), the Super NES (SNES), or for personal computers, while others were released on two or more of those platforms. The "Mario" educational games were generally designed for use by children in preschool or kindergarten and  focused on developing skills ranging from language and typing to geography and history. The educational games were not well-received, with many critics and gamers labeling them as some of the worst "Mario" games ever made. Many of them have spawned Internet memes. Section::::"I Am a Teacher: Super Mario Sweater". is a Famicom Disk System game released in 1986 only in Japan. It was designed by Royal Industries Co., Ltd., a Japanese appliance and sewing machine company. Using the program, players could design the sweater they want and the company would make it for 2900 yen (~$24). Mario Discovery Series . The "Mario Discovery Series" is a label given to five "Mario" educational games that were developed by The Software Toolworks. Section::::"Mario Is Missing!". Mario Is Missing! is a geography-based game released in 1993 for the PC, Macintosh, Super NES and NES. The NES version was developed by Radical Entertainment, while the other versions were developed by The Software Toolworks. In the game, Bowser sets up a castle in Antarctica, and plans to use hair dryers to melt the continent's ice and flood Earth. He sends Koopas to cities across Earth to steal artifacts to fund his operation. Mario , Luigi and Yoshi travel to Bowser's castle to stop him. Mario is kidnapped by Bowser, prompting Luigi to rescue him. Luigi progresses through the game by completing levels in Bowser's castle; each floor is guarded by one Koopaling and contains a number of pipes which transport Luigi to a city containing Koopas. Once a floor is completed, Luigi must defeat the Koopaling guarding that floor to go ahead to the next. The main gameplay consists of moving around a city in side-scrolling manner while jumping on Koopas to collect stolen artifacts (pieces of famous landmarks). Luigi then  must "secure" the city by taking these artifacts to their respective locations and correctly answering two questions about the landmark. Once an artifact is returned, the landmark is reopened. "Mario Is Missing!" is the first "Mario" game to feature only Luigi as the starring character, which did not occur again until "Luigi's Mansion", a game released for the Nintendo GameCube in 2001. Section::::"Mario's Time Machine". Mario's Time Machine was originally released on MS-DOS but later released on the NES and Super NES. The MS-DOS version was re-released as "Mario's Time Machine Deluxe" in  1996. In the game, Bowser steals artifacts from various points in history using a time machine and Mario must return them back. "Mario Is Missing!" and "Mario's Time Machine" were generally poorly received. Section::::"Mario's Early Years!" games. The Mario's Early Years! games were released for the Super Nintendo Entertainment System and computers. The three games were Mario's Early Years! Fun with Letters; Mario's Early Years! Fun with Numbers; and Mario's Early Years! Preschool Fun (known in the United Kingdom as Mario's Playschool). The games were released in September, October, and November 1994, respectively , and all support the SNES Mouse peripheral. The games contain Mario, Princess Peach and Yoshi on a wooden boat traveling from island to island, learning about various subjects. All three games use the same game engine. Section::::"Mario Teaches Typing" games. Mario Teaches Typing was released on personal computers and was designed to teach typing skills to children. The game was developed and published by Interplay Productions. It was first released for MS-DOS in 1992 and then for Windows and Macintosh in 1994. Mario is voiced by Ronald B. Ruben in the floppy disk version and by Charles Martinet in  the CD-ROM version, making this the first time Martinet voiced the character. The game sold over 500,000 units for the Macintosh. A sequel, Mario Teaches Typing 2, was developed by Interplay and published by Nintendo in 1997. Mario is voiced only by Martinet in the sequel. Gameplay. "Mario Teaches Typing" includes three selectable characters: Mario, Luigi and Princess Peach. The game displays two pairs of hands which show which finger to use; for example, if the player has to type "A", the leftmost finger is highlighted. If the player makes an error, the cursor does not advance until they  enter the correct key. After time ends, the exercise ends and a chalkboard screen appears, displaying statistics on how well the player performed, including words per minute. "Mario Teaches Typing 2" adds additional gameplay features, including a customizable certificate of achievement, color-coded on-screen keyboard, customizable lesson plans, and the Mario head. The CD-ROM release of "Mario Teaches Typing" and "Mario Teaches Typing 2" features a story in which Mario and Luigi encounter a magical typewriter. After Mario incorrectly types a phrase that would destroy Bowser's castle, the typewriter explodes into three pieces. The pieces of the  typewriter are retrieved as the player progresses through the game lessons. When the typewriter is fully repaired, Mario is able to type the phrase correctly, resulting in the destruction of Bowser's castle. Section::::"Mario's Game Gallery". "Mario's Game Gallery" features five traditional games which play very similarly to their real world counterparts but with Mario themes. The player faces off against Mario (voiced by Charles Martinet in his first appearance) in these games. While the game and its re-release "Mario's FUNdamentals" have been praised by some, others consider it to be one of the worst games  to feature Mario. Section::::"Super Mario Bros. & Friends: When I Grow Up". Super Mario Bros. & Friends: When I Grow Up is a children's computer coloring game featuring Mario and Luigi. It was released in 1991 for MS-DOS. Players can paint Mario and other Nintendo characters.
