I'm sure that somebody is going to point me to this question, but my case is different.
So I and my best friend are currently writing a science fiction novel that has many plot twists and "objects" that appear frequently throughout the book. We are still in the drafting stage, while I'm working on another individual writing project.
So we had this brilliant idea of using the characters from my individual writing project and slip it into a single scene in the sci-fi novel. It doesn't provide any meaning to the plot, I just thought it was an interesting easter egg to add in.
So the scene is the MC and her friend are biking, walking, something like that, and all of the sudden, a group runs into their way(the group is the characters from my individual project, btw). The group consists of a strange-looking girl along with 5 dogs. Two of the dogs are disguised and are capable of human speech. The two disguised dogs talk, which is weird.
Overall, I like the concept of the idea. It's really interesting and surprising, however, I want the readers to focus on the plot, the objects that keep popping up, and the patterns. But I do not want them to think that this one scene has any meaning to the story. I don't really want the readers to think that this is a really important part of the story, and let them crack their heads trying to figure what two talking dogs can possibly mean.
Is this too much of a plot distraction?
