Poor Luna, her spots do not glow like her parents and the other bioluminescent lanternfish in the sea. They all can produce blue light because that’s the color that shows up the best in a place where there is very little light. 

Luna always asks, “Why can’t I glow like the others?” Her dad insists that she will grow into it. Her mother assures her that it will come to her one day. 

It’s been hard for Luna to communicate with other lanternfish. They use their bioluminescence to talk to one another. They make flashing patterns to show they are happy or sad. She hopes one day she can make a friend but it’s hard to stand out in the dark. 

One day, Luna goes to the school yard to play hide and seek with the other lanternfish. They hide from one another using bioluminescence to camouflage themselves.  

Luna has swam so far she doesn’t know where she is. She suddenly notices a very bright light heading towards her. She approaches the light.

“Attack you? You were shining your light on me!”

Luna asks how are they going to find the Great Crown Jellyfish.  Vince says a pink vampire squid, may be able to help guide them.

As they are swimming, Luna sees a beautiful bright vampire squid and points it out to Vince.  

"Legends say her crown holds infinite light to protect all of the bioluminescent species of the sea. She may give you some of her light,”says Veronica. 

Veronica shows Luna and Vince how she quickly flashes her lights on and off to confuse her prey and get away from  predators.  

Veronica doesn’t know where the Great Crown Jellyfish lives but knows someone who can help them. They have to find the cookiecutter shark. Luna says that name sounds familiar. 

As the three of them start swimming in search of the cookiecutter shark, Luna realizes that the shark is the one who preys on her lanternfish friends.
