Though in all seriousness, I think the reason these posters are made are to get a laugh out of parents and to garner more attention on the Internet and social media buzz than it is to appeal to children. I still think Zootopia was the master at these parodies, and they knew it, considering they would make these types of posters three times (one for regular films, one for Oscars 2016, one for Oscars 2017)
