So, a couple of days ago there were a few Doctor Who/Mr. Men crossovers released. From what I can tell Dr. Eleventh (novel) and Dr. Twelfth (novel) are unaffected by what I'm about to say as they are just any old story written in a Mr. Men format.

But some of these releases feature a character called Walter the Worm who is a character from the original Mr. Men books. After doing some research I found out that the original series of books were set in an entirely separate fictional universe called Misterland. Does the fact that Walter the Worm is a crossover character from a separate universe invalidate certain stories in the Dr. Men series? The stories which would be invalidated by the change would be The Daleks Chase Walter the Worm, Dr. First and Dr. Fourth''.

By the way, as I am writing this I saw Thread:215070 but it didn't address any of the points I have just made.
