Mandela Effect:
Don’t you remember? He had a “M” on chest
New timeline: Nope, just a plain costume
It was 1942, and he was originally called Super Mouse. He sported a nice bright cape, with an “M” on the chest, or so it seemed in our memories?
In 2005 Apple released the “Apple Mighty Mouse”, and Mighty Mouse won, Apple went back to the “Apple Mouse”, pfew.
