In a little farm, there live the happy, hardworking vegetables. Now that the summer holidays have begun, the baby vegetables can't wait to visit Aquamarine Land. Their school teacher, Ms Lady-finger, has told them about all the beautiful aquatic creatures who live there. Baby Carrot takes all his friends to put their request to strict Mr Carrot. Mr Carrot agrees, and one fine day they all set out together for a fun day at the aquarium.
