The pets try methods from a magazine to get food during their stay on the truck.
The pets notice the food supplies for pets already ran out. So, as they don't know how to get food outside, they buy a book for situations like these (but the magazine was for finding food at the forest, but it was almost the same).
Before reading the book, Charles tries to smell food, he enters into a tree's hole, but he knocks an skunk, and Charles escapes quickly. Here are the methods.
- On a tree, usually there's edible food, like seeds or fruit: Walt finds a good quantity of seeds, enough for like two days. Cliff, due his ability to climb with his claws, searches fruits to launch them onto Charles' basket. But one of the apples hits Charles on the head, leaving him with a mark.
- Fishing is another efficient way to find food: The pets notice a lake not so far the truck, so with a fishing rod (made manually by the pets with a rope and a stick) go to the lake. Walt brings some worms. Cliff tries to fish, but the fish ties him to a very big stone, the rope breaks, making Cliff "fly". Cliff returns and uses a log to punch the fish and catches it (at the caveman style).
- Search for nuts, generally it's easy to find some: They find nuts, but they didn't noticed the nuts were from a very protective squirrel, who punches the pets. The pets fool the squirrel grabbing it from the tail. They steal the nuts, and done.
The pets, after their adventure, come back to the truck. The Louds were searching for them, but when the pets enter thru the window and the Louds enter, the pets were sleeping normally.
