What fun things can people participate in at the Ocean of the Stream of Stories?

From the text:

"... the Ocean of the Streams of Story was in fact the biggest library in the universe. And because the stories were held here in fluid form, they retained the ability to change, to become new versions of themselves, to join up with other stories and so become yet other stories; so that unlike the library of books, the Ocean of Streams of Story was much more than a storeroom of yarns. It was not dead but alive."
