Sand and Yam Biscuits

So, said Lavender. When are we going to start looking for the Mortal Jellyfish?

It's the Immortal Jellyfish, said Baby Pierre. IM-mortal. That means it doesn't die. If it was a Mortal Jellyfish it would be just like all the other jellyfish.

Alright, the Immortal Jellyfish, said Lavender. Same difference. When?

Tomorrow morning, said Ageless. We'll go to Henley. Tonight we're going back to the library. We can stay there overnight. There are some things I want to take with me and ....

You talk like an old person, said Lavender. How old are you?

Two hundred and ninety, said Ageless. It's my birthday tomorrow.

Lavender looked at Baby Pierre, who looked shocked.

We're older than you then, said Baby Pierre. How come you seem older?

Because I'm more dangerous, said Ageless.

Yes, you are dangerous, said Baby Pierre, thinking of Frog.

Let's go, said Ageless. Soon the library will close.

They hurried back to North Terrace. Lavender couldn't help thinking about what Ageless had said. She wanted to be dangerous too. But she couldn't think of anything dangerous to do.

They were soon in the reading room at the library. Ageless shuffled around gathering books and tins of biscuits, and then discarding them only to pick them up again.

Which book? he muttered. Which tin?

Baby Pierre grew impatient.

Take the book about Sand, he said, and the tin of Yam bicuits.

Alright, said Ageless. Sorted. Now let's get some sleep.

Baby Pierre wasn't used to sleeping, but he decided to give it a try.

Now Lavender, said Ageless, you can sleep....hey! where's she gone?

But it seemed that Lavender had vanished.
