A young girl found herself in love with anything related to the sea, and often, she'd imagine what it'd be like to see it with her own eyes. This affection often leaked into her day-to-day activities. Sometimes, she'd introduce herself with a fact about the sea then her name. Or she'd tantrum over a sea animal plushie of any kind at the toy store. When she was older, she found out that pearls were her birth stone and couldn't be happier. Everything just attributed to the sea that'd she most likely never lay her eyes upon.
One day, as she brought her favourite dolphin Pillow Pet to her best friends' house, she received her new nickname. Everyone thought it was hilarious that her dolphin Pillow Pet was rather fat for a dolphin. It was shaped like a pillow... of course, it was going to look fat. However, that didn't stop her friends from calling it a whale. Being the sea-lover that she was, she continuously had to remind them that it was indeed a dolphin.
Eventually, she just gave up and named the Pillow Pet "Whale". Whale the fat dolphin.
And even as she reaches adulthood and responsibilities, she's kept her childhood Pillow Pet. She kept Whale the fat dolphin and adopted it as her alias. She's now incredibly used to people calling her Whale. She doesn't take it as a a form of offense because whales are great.
Boom. What'chu got? Is your pen name just as cool? Ahahaha, jokes. WhaleTheFatDolphin is actually super dorky.
