The Treehouse is an educational point-and-click personal computer game developed for the DOS computer and then ported to Apple, Macintosh and FM Towns. It was first released by Brøderbund in 1991 although most copies were sold in educational supply stores instead of mainstream stores that sold computer software and was provided with a Sing-along cassette tape. It was re-released in 1996 for Windows versions 3.1 and 95. Although the Windows version has the same general activities, the characters, interface, and locations are different. Following the success of The Playroom, it was created and provided more content and the user's ability to explore further. In 1993, a game titled The Backyard followed up.
