SPOILER: There is a scene in the closing credits: a Rescue Rangers reunion panel takes place at a fan convention, while they are booed from across the hall by Darkwing Duck, who wants his own show. This is a possible reference to Disney Plus's plans for a Darkwing Duck reboot produced by Bob's player Seth Rogen.
The Disney castle is "bootlegged", transforming it into a patchwork of several different variants of the castle: Elsa's ice palace from Frozen (2013), the Agrabah palace from Aladdin (1992), Prince Eric's castle from The Little Mermaid (1989), and the retro-60s version from Incredibles 2 (2018).
Director Akiva Schaffers credit gets bootlegged, causing four letters to be stylized in the fonts of famous films: the first A in the Indiana Jones font, the I in the Jurassic Park font, the S in the Star Wars font and the R in the Avatar font.
Asides from the Disney Plus Originals logo animation and the Disney logo animation, there are no opening credits after the title is shown.
