The paper said that Morgan needed to help because she was under a spell and Jack and Annie had to find 4 things.

Another clue which Morgan left in the Tree House was an open book.

There was only one open book in the corner of the Tree House.

In the picture there were trees with white flowers and wide and rushing stream and two Ninjas!

Ninjas wore black clothes and had black scarves over their faces.

Jack and Annie thought that the page taught them where Morgan was or where 4 things were.

Jack wanted to find out something from reading the book before leaving, but Annie wanted to go there right now. So Annie wished that they wanted to go there, and then the Tree House whisked them to the place in the picture.
