It’s important to remember that in Curious George, while they applied the name “Ted” to his friend in tbe movie, across all other media he is simply “The Man in the Yellow Hat”. He has no name.
I posit that in prior movies they applied the names “Joe”, “Manco”, and “Blondie”… but he remains the Man With No Name.
The exploration of the world looking for adventure continues… only the hat color has changed.
