I heard that, in a movie called "Frozen", there are some hidden Mickey Mouse.
In the above sentence, I think "Mickey Mouse" should be plural. How would you write it? Mickey Mice? Mickey Mouses? Mickeys Mouse?
I would say "Mickey Mouses." "Mickey Mice" just seems wrong, probably because it is a proper name and not just a description of a small rodent.
"Mickeys Mouse" is incorrect.
You could avoid it all by saying that there are some hidden images of Mickey Mouse.
