The theme change is changeless is shown in Tuck Everlasting. It is shown when the Tucks realize that they can not change the mistake that they made eighty years ago, that ended up changing their lives forever. They know that their is no way, to fix the problem that they had created, and they know that that change they created is changeless, and they have learned to live with that. Also they could not stop the world from changing, while they stayed in their places, stuck in life.

This theme is also showed in, "Urashima and The Princess of The Sea". It is applied in this story because Taro, had to accept the fact that on land, everything had changed, nothing was the same, and he couldn't do anything that would fix that situation. There was no way to get his family back. Even after attempting to use the jewel box, the problems that occurred while he was gone, didn't hid themselves. He couldn't change the things that changed while he was under the sea, there was no way.
