The series' in-universe Precursor language appears in several instances throughout the game, most notably in a series of Story cutscenes. During news broadcasts covering the racing tournament, a news ticker scrolling across the bottom of the screen produces a developer message from Naughty Dog when translated. The message says hello to the player and alludes to save data-based unlockable contents. However, an as-of-yet undiscovered secret is explicitly shared; the message does offer an input code, but to date, no use or purpose for it has been found.

Near the end of the game, a movie called "Hot Coffee" becomes available to buy in the shop. The movie is a 12 second clip of Daxter and Tess drinking coffee. The clip is a parody of the Hot Coffee mod for Grand Theft Auto: San Andreas.
