Some chapters of Shadow Forest didn't make it into the final version. Here are three that got the chop
(click on the links to see the deleted chapters):

The evil log and the colourful wind
Samuel and Ibsen meet the Nøkken and Osterei.

The Aunt Edas
At one point the Changemaker was obsessed by
Aunt Eda and he kept making identical copies of her!

A kind of music
Samuel and Ibsen get caught in the beautiful but deadly
music of the Froogins and a Trunklefish comes to the rescue.

There's more information on some of the creatures found
in these deleted chapters here.
