Ep 13. Free Willzyx

In South Park season 9 episode 13, titled "Free Willzyx," the boys become obsessed with a new attraction at the local aquarium: a performing whale named "Willzyx" who claims to be from the moon. When they learn that the aquarium plans to send Willzyx back into space, the boys hatch a plan to help him return home.

Their plan involves building a rocket ship out of household items and enlisting the help of a group of misguided animal rights activists. Meanwhile, the government becomes aware of their plan and sets out to stop them before they can launch the rocket.

The episode is full of the irreverent humor that South Park is known for, as the boys and the activists encounter a variety of obstacles on their quest to save Willzyx. The episode also touches on themes of animal cruelty and government oppression, but ultimately the focus is on the boys' zany antics and their determination to help their extraterrestrial friend.

As always, the episode features a cast of colorful characters, including the boys' teacher Mr. Garrison, who undergoes yet another bizarre transformation, and the hapless aquarium workers who struggle to deal with the chaos caused by the boys' plan.

Overall, "Free Willzyx" is a standout episode of South Park's ninth season and a testament to the show's enduring popularity and cultural relevance.
