I’m a bit tempted to take this post down because it could fall under our no fetish/kink posting rule. Mpreg is a kink/fetish and this post really isn’t LGBTQ+ either, so it’s off-topic as well. Transmen who are AFAB do sometimes get pregnant, but that is not what is happening in these cartoons.
However, instead, let's turn this into a learning experience. There are some sick people who work in children’s and teen media who really shouldn’t be employed in entertainment made for kids and teens.
When I was younger, Nickelodeon used to feature feet content in their shows. Nickelodeon once even had an orange foot as a logo. The feet content was mostly in their live-action TV shows. The shows were making their children and teen actors/actresses take part in a fetish whether the actors/actresses knew it at the time. It was completely unnecessary and extremely gross.
Fetishes do not belong in kid and teen shows, and I’m sorry there are so many gross adults out there who put it in them. As a world, we really need to do more to protect young actors and actresses as well as kid and teen viewers from being exposed to fetish content. I’m really sorry this happens. :(
