In a previous episode Freddy Spaghetti (2010), when Andy broke his arm and couldn't play guitar, he said Mouse Rat tried playing without him before as Rat Mouse and they suck.
The gorilla statue removed from the putt putt course and left in Ron's office was previously featured briefly in season one episode five of the show 30 Rock.
Leslie refers to the mini golf course as "Putt-Putt." Putt-Putt is a trademarked brand (with the orange rails and all holes are Par 2). The park in this episode is not a Putt-Putt.
Leslie references Toy Story 3 (2010). Rashida Jones (Ann) would later go on to be a writer on Toy Story 4 (2019), but left the project due to creative differences. She is credited as a writer for the original story.
