Picking up at the end of "Storm the Castle", Star Butterfly banishes Ludo through a portal with his own Dimensional Scissors. Floating through the cosmos, Ludo tries to reach a bag of chips before he is hit by a comet, sending him through a portal into a forest. He loses his bag of chips, and tries to get a bird to feed him some insects by throwing one of its chicks out of the nest and taking its place. The bird picks Ludo up and drops him, twice. On the second fall he lands on a spiderweb, where the spider refuses to eat him because he tastes bad, and lets him go.
On Day 37, with nothing to eat, Ludo follows the spider to its fishing hole where it catches some fish. Ludo catches a fish with his beard, but the spider steals the fish and eats it, spitting out its tail which Ludo eats. After trying to get the selfish spider to let him into its cave, Ludo finds his bag of chips, which the spider steals. Ludo fights the spider for the chips. Initially the spider gains the upper hand, but Ludo wins and takes the chips. After eating some of the chips, Ludo feeds some to the spider.
On Day 65, Ludo and the spider are working together, catching fish. They capture the bird, who is on Ludo's side by Day 90. After finally settling down, Ludo is visited by what appears to be Star, and he chases after her with the bird and spider. When he catches up to her, Star disappears but Ludo discovers a magic wand nearby, and realizes he is on Mewni.
- The missing half of the wand's faceplate can be seen on the wand discovered by Ludo.
