As a lot of readers can probably guess, Jenny's neurodivergent little hyperfixation on being underwater is very much autobiographical. I developed my passion for underwater scenes by watching all the same stuff she did - the music videos, the Starburst commercials, the Don Bluth movies. But it wasn't all just stuff I saw on TV. When I was seven years old, I remember I had a dream one night where I was exploring ancient ruins in a cave, and at one point I got so eager to find treasure that I jumped feetfirst into a huge pool of water. Sinking to the bottom and blowing bubbles felt so much fun, and even though it'd be a few more years before I was able to comfortably put my head underwater in real life, I never forgot that dream. So in canon, maybe Jenny had that dream too, and that's what jumpstarted her passion for the water. She's been chasing that high ever since.
