A static model of a blue Opila Bird can be found hidden out-of-bounds, and is referred to as "The Haze" in the game files. It would later appear in Garten of Banban 3 under the name "Tarta Bird".

In 2023, after seeing online backlash towards Garten of Banban for its barebones quality and gameplay, YouTuber UniqueGeese (real name Mason Myers) decided to try recreating the game in a single week to see if game development could be that easy. He would go on to do so over his spring break, and showed the results of his work in a video titled "I Recreated Garten of Banban in One Week", which would go on to become his most popular video. He released the game as "Garten of Banban: Reincarnated", but would later change the name to simply "Reincarnated" per the request of Garten of Banban developers the Euphoric Brothers in order to avoid confusion regarding the original games. The popularity of Reincarnated inspired Myers to create his own unique horror game, resulting in the development of Indigo Park.

Garten of Banban has been noted for poor optimization in its 3D modelling, with the game's models containing absurdly high polygon counts relative to their simplistic designs. The most infamous example of this is a small geometric remote control made up of 184,332 triangles, which is seen for the entirety of the game.

Originally, Stinger Flynn was intended to be the main antagonist of Garten of Banban, but was replaced with the Opila Bird, as the devs felt she would be a better fit.
