[quote="Algi"]Hmmm... I don't think so...

Maybe Disney wrote that book, maybe not, because i never went to Disney.

You don't have to go to Disney to know they didn't write them. Yesterday, I already answered crystally's question in the topic about Scar. That yes, I'm 100% positive that Disney didn't write the books.
I know they weren't written by Disney because I do my research well.
Here, I copy & paste my evidence from the Scar thread.
Alex Simmons, the author of the FIRST book in the "Disney's The Lion King: Six New Adventures" series ("A Tale of Two Brothers") and thus the creator of Kopa, does not work at the Walt Disney Company. He is a writer, actor, playwright, voice-over talent, speaker, and teaching artist who has his own clients and associations and writes for numerous different companies.
"Simmons has written three movie novelizations for Disney..." Disney didn't write them. It released them.
>> Alex Simmons personal web site <<And
this page of his site makes clear that that novel is his original story based on the hit film. As in he created and wrote it and then gave to Disney to make money of and to entertain kids.
I think it would be fairly pointless to go into detail with the rest of the book series' authors. You can research them if you will and find out that they are just professional childrens' book authors whho create and write for those who pay for it, including but not mainly, for Disney.
Nothing about that book series came from Disney except the film(s) the books base on. (And likely nothing about any of the books in the book universe that totally contradicts itself.) Disney just slammed its stamp on them so that it could make money with it and do whatever the heck it wants with them, and apparently Disney wanted nothing more but money out of them as the film makers didn't approve them but denied Kopa's existence in the movie universe.
crystally also questioned
"How did several professional writers wrote separate books in TLK6NA and all have named characters like Kopa and Taka the same? Surely they got it from somewhere if they use the same names."Because by the time the second book was to be written, Disney held copyrights for those characters Simmons had created. Disney may have wanted a book series all along but Simmons and no one wanted to write it all, or Disney wanted each part written by a different author, for whatever reason. The key facts are that Alex Simmons started the book series while he wasn't part of Walt Disney Company and the novel is his original story and not Disney's idea or work at any point (apart from the outlines the film gives.) It wouldn't be his original story based on the hit film, if Disney provided him with anything more than the film itself.
