One idea could be that they discover the pregnancy unexpectedly. Maybe they're still in the midst of dealing with their powers and the challenges that come with them. Rikki could be worried about how her mermaid nature might affect the pregnancy. Zane, on the other hand, would be determined to support her no matter what. They might have to hide the pregnancy from some of their friends at first because they're not sure how to explain it, especially considering their unique situation as mermaids and mermen.
You could start with them having a conversation about their future and wanting a family. Then, Rikki reveals that she might be pregnant. This way, you build up the anticipation before the big news and show their relationship dynamics leading up to this point.

Since I haven't listened to the h3h3 podcast ghost stories directly, I can only speculate. However, in most ghost stories, there are elements of the unknown and the supernatural. There could be stories about people staying in a supposedly haunted hotel room. They might experience lights flickering for no reason, or the feeling of being watched while they are alone in the room. And perhaps the podcast also shares some local legends that have a spooky undertone, like a spirit that haunts a particular bridge because of a tragic event that happened there long ago.
One great short story from Zane books could be 'Flava'. It's a story that delves into the complex relationships and desires of the characters. The characters are vividly drawn, and the plot keeps you engaged from start to finish.
