Consider this a bit of an age question. As hard as I try I can't remember what Storybook was like before the Aladdin addition? and I am also unsure if Little Mermaid was added at the same time? I haven't been on in ages, mainly because nothing has changed.
I often wondered what Walt's plans were; display models, bring his animations to life; refresh with each new feature or simply update for the "big ones". Did he make them small because he loved models, or to fit the theme of Alice when she was a "Giant" and everything shrank?
The other questions are more down to Earth. What is missing, animated feature wise, from the book? How much room is there to add new models? Which older models can be compressed, downsized, or re-themed to make new models? should anything at all be done to it since it has achieved "classic" status?
