Quick facts about Little Nemo: It was originally a comic strip in the early 1900's by Winsor McKay. He was a pioneer in cartooning and was diong animation when Disney was in diapers. Have you ever seen the black and white silent cartoon Gertie the Dinosaur? That was Winsor McKay! Before he did Little Nemo he designed circus posters and also took his animation to vaudeville. You can see that in his art style of Little Nemo. Other comics he did were Sammy Sneeze and Dreams of a Rarebit Fiend.
Even though the Little Nemo NES game is actually based on a Little Nemo anme from the early 90's, it has elements of the comic strip, too. The first stage in the game is called "Mushroom Forest." That area is nowhere in the anime movie, but it was one of the first places Nemo visited in the comic strip! Capcom also made an arcade Little Nemo game in Japan that is totally different from the NES version. A comic book company recently made a brand new Little Nemo series of comics. I have yet to read them, but I have a hardcover collection of them reserved at a comic book store when it comes out.
I suggest looking up more infomation on the internet if you want to know more about Little Nemo. I think it's pretty interesting.
