I'm not sure specifically as there could be many stories related to 'Peter' with a never - ending theme. It might be about Peter's adventures that keep going on without a clear end, like his continuous exploration of a magical world.
I'm not entirely sure which specific 'Peter Griffin Never Ending Story' you are referring to. It could potentially be a fan - made or very niche story related to Peter Griffin from 'Family Guy'. Maybe it's a creative exploration of his character in an ongoing, never - ending narrative.
One of the main themes is the idea of eternal youth. Peter Pan never grows up and represents a carefree, youthful spirit. Another theme could be the concept of adventure. The story is filled with exciting escapades in Neverland. Also, there's a sense of magic and the extraordinary, from flying to fairies like Tinker Bell.
Peter Pan himself is very memorable. His ability to fly and his eternal youth make him stand out. Also, Captain Hook with his hook hand and his constant pursuit of Peter is quite unforgettable. And Tinker Bell, the feisty little fairy who is both helpful and jealous at times.
As far as I know, there may not be a 'Never Ending Story 3' officially released. But the film industry is always evolving, and new projects can come up unexpectedly.
