Giant fish with legs and a cat head

A colossal fish equipped with robust limbs, likely equivalent to the back legs of a cheetah for enhanced speed and agility. This aquatic creature boasts a feline head peculiarly similar to that of a Maine Coon, characterized by hairy tufted ears and sharp, piercing green eyes. The fish aspect of the creature possesses shimmering turquoise scales to lend an aquatic touch.
