Development and unveiling
originally began as an interactive multiplayer role-playing game that focused on cooperation among players to reach common goals. The game was to be developed for the Nintendo 64DD and would take advantage of the system's expanded memory and internal clock. As the market for the 64DD began to wane, the project was ported over to the Nintendo 64. Due to the memory limitations now faced, many aspects of the original game had to be completely redesigned.

The original title featured a "helpless" character who had to enlist the help of animals to make their way through the game. These animals' sleep and wake cycles would be affected by the built-in clock. The designers ended up removing many of the goal-oriented elements from the game including dungeons, bosses, and monsters, leaving only the core aspects of communication and the idea of an environment that operated in real-time. Working within the limitations of the Nintendo 64, the team relied on an open-ended and addictive gameplay experience that would keep the player coming back, as opposed to a goal-oriented approach. To accomplish this, the team included a variety of large and small tasks for the player to accomplish, to provide a sense of satisfaction for all play styles.

In an interview with IGN on June 5, 2000 about upcoming Nintendo software and hardware, announced the development team was working on a "communication game" for the Nintendo 64 but did not elaborate. was fully unveiled at in August, with a planned release of month of February 2001  and a demo playable on the show floor. The game was later delayed from its planned February 2001 release and its final release date of April 14, 2001 was revealed in March 2001.

Release

The included Controller Pak in the bundle features a Grab Bag and a letter from Shigeru Miyamoto, who supervised the development of the game. The Grab Bag contains two random Famicom games and a random K.K. Slider song, while the letter can be accessed at the post office. It reads:


 * "どうぶつのもり みやもとさん


 * カセットそれぞれに じぶんのむら があり、くらしをたのしむゲームが できました. つよいボスとたたかう こともないので、ひとりよりふたり ふたりよりおおぜい!かぞくや、お ともだちと おたのしみください. 


 * にんてんどう みやもとしげるより"

Which translates to:


 * "Animal Forest Miyamoto-san


 *  Each game cartridge has its village, where you can enjoy a virtual life. There aren't any strong bosses or crowds of people. Please enjoy it with your family and friends.


 *  Yours, Shigeru Miyamoto, Nintendo"

Gameplay
Players assume the role of a human setting out for a life of their own in a town of anthropomorphic animals. Each town is randomly generated, ensuring that no two players' experiences are the same. Gameplay within each village is open-ended allowing players to engage in a variety of activities that suit their playstyle. Players can pick fruit, grow trees, garden, hunt for fossils and fish, catch insects, do favors for the villagers, or decorate their homes. The game runs in real-time, and gameplay is affected by the time of day and year; as the Nintendo 64 lacks a built-in internal clock, time is kept via a chip inside the Game Pak powered by a CR2032 battery, allowing the clock to continue running even when the game is turned off. If the battery dies or is removed, the game will start up with K.K. Slider informing the player that the clock has stopped working, at which point they must configure the date and time manually.
