Animaniacs: Wakko's Wish (known as just Wakko's Wish) is a direct-to-video movie that stars the cast of Animaniacs in a fantasy setting. It was released on December 21, 1999 on VHS, and has been rerun on television on occasion. It was released on DVD on October 7, 2014. 
In the town of Acme Falls within the kingdom of Warnerstock, all the Animaniacs characters (and a mime) live happily together. However, upon the death of the king, Sir William the Good, Warnerstock enters a state of civil war. Taking advantage of the situation, the neighboring fictional kingdom of Ticktockia (a parody of Time Inc., at the time of its merger with Warner Communications), led by King Salazar the Pushy, takes over Warnerstock, and makes all its citizens (including the Mime) poor and miserable due to overtaxing.
Three orphans, Yakko, Wakko, and Dot Warner, are particularly troubled, as Dot needs an operation. So Wakko decides to find work in another town to pay for it. He returns a year later with a solitary ha'penny, which is more than enough to buy him anything he wants. His joyus return is cut short by Baron Von Plotz, takes Wakko's ha'penny right out of his hands, lying that it's for taxes.
That night, in their broken down water tower shanty, Dot asks Yakko to tell her the story about Mom and Dad before going to bed. The story involves Dot's birth, her parents being king and queen who had two sons, but wanted a daughter Dot was born from the prettiest flower in their garden, and while her full name was "Princess Angelina Contessa Louisa Francesca Banana Fanna Bo Besca The Third", it was okay to just call her "Dot", and anyone who called her "Dottie" would die, Yakko tells Dot that their parents laughed when she said it and they tickled her, then she fell asleep with a smile in her heart. After Dot is put to sleep, and Yakko turns in for the night, Wakko looks up at the sky and makes a wish on the Wishing Star, hoping for a miracle. Suddenly, he's visited by a fairy (who calls himself a "desire fulfillment facilitator" or "Pip") who explains that Wakko had just managed to choose the Wishing Star, and will be granted one wish. However, because wishes have to granted in person, Wakko needs to seek out and touch the star. The star itself [which Rita and Runt witness] falls miles away, outside of town. Then, Pip leaves, reminding Wakko to never give up hope. After that, Dot and Yakko arrive to find out what happened. When Wakko tells them they'll never believe what just happened, Yakko responds "Try us. We're gullible."
The following morning, the siblings tell the whole town about the star in their excitement, which makes them all rush towards the glow in the mountains, each wanting their own wish granted. King Salazar finds out about the star, orders Taxman Plotz to stop the Warners from reaching the star alive, and orders his troops to head to the star first and secure it.
Plotz doesn't manage to stop the Warners from reaching the star at the same time as all the other townsfolk. The King's army has already built a military base around the star's location, and a small ice palace to the side of it. He then has the townspeople (including Plotz) captured and locked up so that the King can make his wish. The Warners hint that the wishing process is not as simple as the king thinks in a desperate bluff. The King captures the Warners and tortures them with "The cave of your worst nightmares", which features many Animaniacs antagonists (such as Baloney the Dinosaur). After being traumatized, The Warners confess to the King, telling him that any wish he makes could have an ironic twist and demonstrate this to his annoyance. He orders the Warners executed, but Dot uses her cuteness to get the guards to release them.
As the King is about to make his wish, the Warners try to run towards the star. Upon seeing this, he tries shooting them himself with a cannon. Yakko and Wakko were only knocked back by the explosion, but Dot appeared to be hit. Wakko seizes his chance to head to the star, and Yakko falls behind, trying to convince Dot that she can make it. Yakko then tearfully tells Dot the story of how she was born one last time. Dot then seemingly dies, causing the people of Acme Falls to cry in sorrow, along with some of the royal army, who become furious at King Salazar for his cruel nature. As everyone turns on the King, who shows a little remorse, Wakko reaches the wishing star. Then, Dot reveals that she had been faking it the whole time to buy time for Wakko, who then wishes for two ha'pennies.
Wakko uses the first one to buy food and "season tickets for the Lakers." He uses the second one to pay for Dot's operation, which is revealed to be a plastic surgery to give her a beauty mark, which she called a "Cutie mark". Wakko's first ha'penny, however, returns prosperity to the town as the butcher, the baker, and the candlestick maker start spending the money they've just 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 were indeed the heirs to the throne. Their parents (seen for first and only time in a portrait) were the king and queen of Warnerstock. They then boot Salazar out of their palace (literally) where he is attacked by his own dogs as punishment. The movie ends showing how the Warners use their new-found royal authorities to grant the citizens of Acme Falls (except for the Mime) their wishes. Before the credits, everyone spins the Wheel of Morality. The moral of the story is "Just cheer up and never ever give up hope."
