Learn You a Haskell for Great Good! (http://learnyouahaskell.com/chapters http://learnyouahaskell.com/chapters) is one of the better gentle into to haskell guides. I think it started attempting to be sort of similar to why's guide but ended up being a lot more straightforward although there are still some whimsical examples and pictures.
