Was that a Snoofy reference?

Harper is in love with tv, movies, music and books, but sometimes I wonder if we are taking in the same thing.  She changes names, plots and stories to the point that I wonder what in the world she is talking about.  In addition, she will cling onto one minor point and talk about it (and talk about it, and talk about it!)  You can correct her, but she sticks to her story (movie, music or book!)
For instance, Charlie Brown has a dog named "Snoofy"
In the movie "Cars" the main character is "Lightening and the Queen"
In "Rudolph the Red Nose Reindeer", the snow monster is the "Avondorable Snow Monster"
In the Nutcracker, the prima ballerina is "the Sugar Fun Fairy"
"You better watch out, you better not cry, you better not cry, I'm telling you why, Santa Clause is coming to town!"
"Rudoph has a red nose, and Santa tries to knock it off!"
We have a book about a little African-American boy who goes out into the snow.  Harper sees a page that has a picture of the boy with his bare foot in the snow.  Harper is convinced that his foot is poop.  Lucy finds this endlessly funny and has us read the book, just so Harper will point out the "poop".
