Mertini's Ocean Olympics — Wendy Lee

A young octopus named Mertini and friends who include a sea turtle, a hammerhead shark, and a dolphin compete in the school olympics. Mertini has never won the gold medal, but now has a secret weapon--a training coach, Kali the orca. The only thing in Mertini's way is an octopus named Jax who is very athletic and competitive, and also a bully. Jax has won the gold medal two years in a row. Mertini must train hard, eat yucky-looking vegetables, and get a good night of sleep during training. Will Mertini finally win the gold, or will Jax cheat his way to victory? This book teaches children good lessons in life and to never give up on their dreams.
