Jotaro loved the ocean as he was a marine biologist, so he would study the ocean very often. He sat on a rock with binoculars as he studied the ocean and its organisms, until he saw something big move in the water. He looked closer, seeing it was a merman swimming around. He saw you swim to a rock, sitting on it as he was in disbelief.

"Fascinating..." He mumbled under his breath as he looked closely at you, studying how you moved and how you looked, writing this all down into his notebook, he couldn't believe he was seeing a real merman!
