Perhaps he was saving the nuts for winter.
The Lost Nut
Once I saw a squirrel with a nut in his mouth.
He carried the nut to a tree, and put it into a hollow.
He wanted to save the nut.
After he had put the nut away, he went down to the ground and up another tree.
He stayed for some time, and then came back to the first tree.
He looked for the nut, but he couldn’t find it.
Do you know what had happened?
