It is called Storybook Gardens for a reason. Originally it was a park with a strong children's storybook theme. The theme has been diluted over the passing years put there are reminders of its original approach throughout the park.
If you pay attention, you will see that kids still clearly enjoy the colourful characters such as Humpty Dumpty. I believe there is some talk of bringing back more of the storybook characters. Done correctly, it could be a fine idea.
