The Louds meet a tribe that are exactly like them.
The episode begins with Lily crying because she wants milk. Lincoln, worried, he runs to make a wooden bottle. Then Lincoln finds a cow that was lost on the island because he was in a part of corral within the sea, and start to get some milk.
This one arrives and gives the milk to Lily, the Louds are tired because he returned at night, so Lana attaches the cow to a tree and they go away to sleep in some forts that had built.
The next day, everyone wakes up, just to see that the cow was not tied and the rope was on the ground.
The Louds search in the island, and they see a family native to it, almost identical to the Louds, with 13 people in the family. 10 played to be Indians and their mother and father took an original "mate" from Argentina, while the other played a video game that they found called "Monkey 2: Island Adventure".
The Louds decide to ask the family, if they had "their" cow, until they reveal that the cow was the family's pet.
The Louds seem to like the family just known, and the similar family invites them to take and eat something, the Louds thank them because they did not had breakfast.
Later, Lincoln and Frank (named after the middle son) wandered all over the island on a tricycle they built with things from nature.
