Enid Blyton's Enchanted Lands (1997)

When the children climb the Faraway Tree they discover it is inhabited by different magical creatures, including Moon-Face, Silky the fairy, The Saucepan Man, Dame Washalot, Mr. Watzisname and the Angry Pixie. They befriend some of these creatures, in particular Moon-face and Silky. At the very top of the tree they discover a ladder which leads them to a magical land. This land is different on each visit, because each place moves on from the top of the tree to make way for a new land. The children are free to come and go, but they must leave before the land moves on or they will be stuck there until the land returns to the Faraway Tree.
