Editing Story within a story (section)

== From story within a story to separate story ==
Occasionally, a story within a story becomes such a popular element that the producer(s) decide to develop it autonomously as a separate and distinct work. This is an example of a [[Spin-off (media)|spin-off]]. Such spin-offs may be produced as a way of providing additional information on the fictional world for fans.

In ''[[Homestuck]]'' by [[Andrew Hussie]], there is a comic called [[Sweet Bro and Hella Jeff]], created by one of the characters, Dave Strider. It was later adapted to its own ongoing series.

In the ''[[Toy Story]]'' film universe, [[Buzz Lightyear]] is an animated toy action figure, which was based on a fictitious cartoon series, ''[[Buzz Lightyear of Star Command]]'', which did not exist in the real world except for snippets seen within ''Toy Story''. Later, ''Buzz Lightyear of Star Command'' was produced in the real world and was itself later joined by [[Lightyear (film)|''Lightyear'']], a film described as the source material for the toy and cartoon series.

''[[Kujibiki Unbalance]]'', a series in the ''[[Genshiken]]'' universe, has spawned merchandise of its own, and been remade into a series on its own.

The popular ''[[Dog Man]]'' series of children's graphic novels is presented as a creation of the main characters of author [[Dav Pilkey]]'s earlier series, ''[[Captain Underpants]]''. 

In the animated online franchise ''[[Homestar Runner]]'', many of the best-known features were spun off from each other. The best known was "Strong Bad Emails", which depicted the villain of the original story giving snarky answers to fan emails, but that in turn spawned several other long-running features which started out as figments of Strong Bad's imagination, including the teen-oriented cartoon parody "Teen Girl Squad" and the anime parody "20X6".

In the ''[[Harry Potter]]'' series, three such supplemental books have been produced: [[Fantastic Beasts and Where to Find Them (book)|''Fantastic Beasts and Where to Find Them'']], a guidebook used by the characters; ''[[Quidditch Through the Ages]]'', a book from the school library; and ''[[The Tales of Beedle the Bard]]'', presenting fairy tales told to children of the wizarding world.

In the works of [[Kurt Vonnegut]], [[Kilgore Trout]] has written a novel called ''[[Venus on the Half-Shell]]''. In 1975 real-world author [[Philip José Farmer]] wrote a science-fiction novel called ''Venus on the Half-Shell'', published under the name Kilgore Trout.

''Captain Proton: Defender of the Earth'', a story by [[Dean Wesley Smith]], was adapted from the holonovel ''[[Captain Proton]]'' in the [[Star Trek]] universe.

One unique example is the [[Tyler Perry]] comedy/horror hit ''[[Boo! A Madea Halloween]]'', which originated as a parody of Tyler Perry films in the [[Chris Rock]] film ''[[Top 5]]''.
