Marco wants to show Star the geyser ?Old Youthful? during a Diaz camping trip. King Butterfly joins them on the trip to learn what Earth camping is like. But King Butterfly's antics get him in trouble several times with the park ranger. When Marco reveals he wanted to show Star the geyser, and the ranger says it's likely the last time it will ever erupt, the three try to rush there to see it.
After having skirmished with a number of dangerous monsters, Star Butterfly arrives on Earth to live with the Diaz family. However, rather than living a normal life, Star continues on having to battle villains both throughout the universe and in their high school, although if only to protect her extremely powerful wand, an object which she is still confused with.
