Toby is a Goby fish from Hawaii. Though he was born in the salty ocean, his destiny is to be a fresh water fish. His friends help him remember that he is a special and extraordinary fish, and he'll need to remember this, because the journey to his new home is going to be hard.

Toby will grow big and strong, fast and brave and one day make his way up a waterfall to the top of a mountain stream. He will have some thoughts about himself that aren't very nice, and when he believes these, he doesn't feel like trying. But Toby's friends help him remember who he is, that he is never alone, and soon he learns to splash and sing in the bright sunlight. Do hard things. Swim upstream. Follow the Son, and be a Goby!
