Official Bio
"Destiny may be a clumsy swimmer, but she has a big heart. She has a big everything, actually — whale sharks are the biggest fish in the sea. Destiny resides in the Marine Life Institute, where one day an oddly familiar blue tang named Dory falls into her pool. Destiny is admittedly embarrassed by her obvious lack of grace, a product of poor eyesight, but Dory thinks she swims beautifully. And Dory is delighted to learn that her supersized friend speaks whale, too."
