Little boy meets Mickey Mouse 'in real life' for the first time

Do kids really care if it’s Minnie, Mickey, or any other delightful mascot focusing on and hugging them? Unless advertising and media implanted the idea that only A-class cartoon characters (or Santa Claus) are worthy of consideration?

I mean, how old is that kid? 3, 4 years? It’s unlikely that they will even remember the incident, even with film evidence.
