In the town of Acme Falls within the kingdom of Warnerstock, all the people (including the mime) live happily together.

However, upon the death of their beloved king, Sir William the Good, Warnerstock enters a state of civil war.

The cannonball explodes after landing just short of hitting the Warners, but Dot is mortally wounded and asks Yakko to tell her the story of how she was born one last time.

Dot appears to die, causing the people of Acme Falls to cry in sorrow, along with some of the royal army.

The Captain of the Guard becomes furious with King Salazar and gives him an angry speech calling him out for his cruel nature.

Wakko's first ha'penny, however, returns prosperity to the town as the butcher, the baker, and the grocer spend the money that they earned, and the people from whom they make purchases in turn do the same.

The hospital finds Yakko, Wakko, and Dot's birth certificates, and reveals they are the heirs to the throne of Warnerstock.

[3] Wakko's Wish was originally slated for its VHS release in November 1998, but was pushed forward to December 21, 1999, and re-released on January 25, 2000, as part of the Warner Bros. Century 2000 Collection.

Brett Rogers of AOL Hometown gave the film a positive review, saying that "[t]here’s a lot about this movie that will please die-hard Animaniacs fans," noting the appearances of almost all of the main characters and antagonists of the original series.

Rogers pointed that the pathos not usually seen in the series may leave some Animaniacs fans distant from the film, but that the serious tone is "backed up with superb voice acting," by Paulsen and Harnell.

"[11] Michael Stewart of Entertainment Weekly found that the lack of the typical Animaniacs humor was positive, saying that the film "avoids the forced wackiness that plagues the television series," while "deliver[ing] some laughs for both kids and adults."

[13] In 2000, Wakko's Wish was nominated for four Annie Awards: One for "Outstanding Achievement in An Animated Home Video Production", one for "Outstanding Individual Achievement for Music in an Animated Feature Production" (Richard Stone, Steven Bernstein, Julie Bernstein, Gordon Goodwin & Timothy Kelly), one for "Outstanding Individual Achievement for Voice Acting By a Female Performer in an Animated Feature Production" (Tress MacNeille), and one for "Outstanding Individual Achievement for Voice Acting By a Male Performer in an Animated Feature Production" (Maurice LaMarche).
