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.

If the player presents the Rambley Mask collectible at the Information Kiosk, Rambley will play an audio recording of two employees (one of whom is named Jackson and is referred to as "Old Sport" by his colleague) complaining about the new mascots before deciding to quit their jobs and move to Las Vegas. This is a reference to the Five Nights at Freddy's fangame Dayshift at Freddy's, where the game's "Gnarly Ending" sees the player and Purple Guy escaping the pizzeria as it burns down before deciding to move to Las Vegas. The creator of the Dayshift at Freddy's series, DirectDoggo, acknowledged the reference on Twitter, stating he felt speechless about it.

There is a miniature model of Lloyd the Lion located in the back of the Lloyd's Main Stage Theater area. According to the game's creator UniqueGeese, he couldn't remember why exactly it was there, but theorized that he was simply testing the model and forgot to remove it due to how small it was. He added that he likely won't remove it because "it took forever for people to find it."

The Poodle Plush collectible item is based on Percy Poodle, the titular antagonist of the Five Nights at Freddy's fangame Playtime with Percy. Rambley alludes to this when presenting the plush to him at the Information Kiosk, noting how it's a "non-Indigo-brand toy", and claiming that it would "make playtime special for a child with poor taste".
