Please note there are some gaps in my notes from the last Storybook, but I'll be able to fill most of them in gradually. I do NOT speed through the story, so some of the missing information for later chapters will have to wait until I unlock them. Also, some acts always auto-complete for me (e.g. raising animal, tournament progress, etc), which makes it hard to patch details.
Areas in red indicate where lower-level forests have different or reduced tasks.
You will usually need to collect fewer items from harvesting, evolving and mining;
You won't have to raise the 2nd prize animal (Will o' Wisp) as high;
Your Ch.9 breeder will be different ( Aquatter instead of Bamboon);
Your cost (in gems) to skip SOME tasks will be lower; cost to unlock chapters early seems to be the same;
Some tasks (or portions of tasks) will not be required of you.
Whenever it says "Feed any animal n times" it does NOT need to be the same animal; you can split the feeding among multiple animals.

CONFIRMED: Skipping costs that appear in blue are actually HIGHER for lower-level forests! Is it an error long overlooked? You may want to join me in asking Storm8: WHAT'S UP WITH THAT?!!
Please bear with me as I continue to fill in any remaining missing details.
