One day while taking a swim, Marlin and Nemo are looking around when they hear a baby crying. They go over and find a baby mermaid, it is clear that she was kidnapped. They find a necklace on her and it says that her name is Naia.
"We can't leave her here, aw she's so cute," says Dory.
"You're right, let's take her in and I will spread the word that we found her," says Marlin.
They scoop her up, helping her to their place where they are introduce Nemo to her. Nemo really likes Naia and offers to help her find her parents Naia loved the attention that she was getting. She missed her mommy and daddy so much that she didn't really respond to the three of them the first two days. Though she slowly started to open up to them on day three. They wanted her to know that she wasn't in any danger before taking her out to the town to see if anyone knows who her parents were. They couldn't find them no matter what they did, Dory did bring it up to her fish are friends not food meeting after a month of searching on their own.
"Aw, we will help you find her parents, Dory," says Bruce.
"What's her name?" asks Chum.
"Naia," says Dory.
"What's she look like?" asks Anchor.
"Uh….*she thought really hard on this one* short brown hair, blue eyes, and a pink tail. She is also wearing a necklace with her name engraved on the back of it," says Dory.
"Got it!" says the boys.
"Thanks guys, your the best!" says Dory.
In the meantime Marlin and Nemo are getting Crush and Squirt to look for her parents too. It wasn't hard to convince either of them to look for baby Naia's parents. After Dory's meeting they went home to where Naia was, she was awake and crying up a storm. Nemo tried to help Dory and Marlin as long as they could but he was getting tired. Marlin tells him to go to bed as Dory is rocking Naia.
"What if we sing to her?" suggests Dory.
"Sing?" asks Marlin, "Sing what exactly?"
"We will make something up, here I'll start," says Dory.
She sets Naia in bed making sure she is comfy.
"Hush and stop the tears of will be okay, If you'll behave I will guide you to a beautiful you sleep, you'll glow in sun needs to rest under the sun doesn't need to hear a racket. You'll be alright if you close your angelic eyes. When you do that, the moon will set in rise," sings Dory.
