I followed Sweetgi but backstory time Temper loved swimming with the water creatures. Other cats called her crazy for loving water. Her mother scolded her multiple times. One day, Temper wandered out too far, and was swept into a ravine underwater. She figured out she could breathe underwater with a special pearl, witch gave her powers. She happily spends her days conjuring waves and surfing.
The backstory reminds me of Percy Jackson and Moana.
