Ep 9. Baby

Star vs. the Forces of Evil season 3 episode 9, titled "Baby," follows the adventures of Star Butterfly, a magical princess from the dimension of Mewni, as she navigates her way through high school on Earth. In this episode, Star's wand accidentally transforms her father, King River, into a baby.

The episode opens with Star, her best friend Marco, and her boyfriend Tom attending a concert by their favorite band, Love Sentence. However, Star's excitement is quickly dampened when her parents, River and Queen Moon, show up unexpectedly. They inform Star that they have been dealing with a dangerous monster invasion in Mewni and have had to evacuate their castle, leaving their baby daughter, Meteora, behind.

Feeling overwhelmed by the responsibility of taking care of their baby sister, Star and Marco decide to take a break and head to the mall. However, while they are there, Star's wand accidentally hits her father, turning him into an infant. This leaves Star and Marco in a panic, as they have to find a way to change him back before her parents find out and panic themselves.

The rest of the episode revolves around Star and Marco's efforts to keep King River out of harm's way while searching for a way to reverse the transformation. Along the way, they encounter a variety of obstacles, such as navigating a crowded mall and running into nosy classmates.

As they search for a solution, they come across Buff Frog, a former monster general who has defected to their side. Buff Frog reveals that he knows of a powerful magical object that may be able to reverse the transformation. With his help, Star and Marco embark on a dangerous mission to retrieve the object.

Meanwhile, King River's new baby form proves to be a handful. He constantly cries and demands attention, making it difficult for Star and Marco to keep him hidden. They eventually enlist the help of their friend Janna, who is known for her mischievous behavior, to distract their classmates and keep King River out of sight.

Ultimately, Star and Marco are able to retrieve the magical object and successfully reverse King River's transformation. However, they soon realize that they may have made things worse. The magical object had unforeseen consequences, and now River has transformed into a much larger and more dangerous version of himself.

The episode ends on a cliffhanger, with the fate of Mewni hanging in the balance. Star and her friends must now band together to save the kingdom and stop the monster invasion before it's too late.

Overall, "Baby" is a thrilling and action-packed episode that showcases the strength of Star and her friends' bond. It is also a reminder of the power of family and the lengths we will go to protect those we love.
