Sequel is the inventively titled "The Book of Unwritten Tales 2". I regard the prequel (The Critter Chronicles [TCC]) as a sequel as well and just didn't find the humour in that one, especially, as good as the first game. I haven't played any of them for years now but from memory I found TCC a bit easier than the others as well.
I dunno where I came across my avatar, but it's here:
