Mei’s Mermaid Mission

Mei is a proud member of the Mermaids International Rescue Alliance (MIRA), and she’s been assigned a high-stakes mission: gather her team and swim to the East Sea, where a notorious troublemaker, Pirate Polymer, is polluting the ocean and putting marine life in danger.

Along the way, Mei and her fellow mermaids encounter a series of urgent environmental problems that many children have heard about but may not fully understand: an oil spill that destroys a manta ray’s habitat, fishing practices that threaten seahorses, a whale shark made sick by plastic, and coral bleaching that turns reefs white.

As the mermaids get closer to their destination – passing memorable sea creatures and recognizable locations like Jeju Island – they finally confront Pirate Polymer. What follows is a satisfying moment of problem-solving and accountability that emphasizes a powerful idea for young readers: people can learn, change, and help repair the damage they’ve caused.

Why it works so well for kids (and the adults who read with them)

Even though the book is playful and fantasy-filled, the conservation message lands with real impact. The environmental issues are presented in a way that feels concrete and understandable, making this a strong pick for read-alouds that lead naturally into discussion.

Just as meaningful is the book’s cultural richness. Names and references draw on Asia-Pacific mermaid traditions and legends, including figures associated with places like Korea, Malaysia, and Indonesia, alongside historical touchpoints such as Madame Ching (one of history’s most successful female pirates). The story also nods to specific locations across countries such as India, Vietnam, and Sri Lanka, inviting children to see the ocean as a force that connects communities worldwide.

Classroom, library, and home connections

This is an excellent story for:

  • Earth Day/ocean conservation units
  • SEL themes like responsibility, empathy, and being part of a solution
  • Global learning and “mirrors & windows” reading experiences
  • Nonfiction text features practice, thanks to the book’s extensive glossary (great for vocabulary building and research mini-lessons)

Mei’s Mermaid Mission is the kind of picture book that sparks curiosity on multiple levels: readers learn about marine animals, understand real threats facing ocean ecosystems, and encounter cultural references that widen their sense of the world.

For a Read Your World event, it’s a wonderful example of how diverse children’s literature can be both joyful and deeply meaningful – encouraging kids to care for the planet and appreciate stories rooted in many cultures.

Post-Reading Discussion Questions

  1. Mei and her team saw several ocean problems. Which one felt the most serious to you, and why?
  2. Cause and effect: Pick one problem (oil spill, nets, plastic, coral bleaching). What caused it, and what happened to the animals because of it?
  3. Pirate Polymer changes his actions. What helped him understand the impact of what he was doing? What do you think made him willing to change?
  4. Teamwork: How did the mermaids work together during the mission? What strengths did different characters bring?
  5. Point of view: Choose one ocean animal from the story. If it could talk, what would it want humans to know?
  6. Real vs. fantasy: The story uses mermaids and pirates. How did the author use fantasy to teach something real?
  7. Problem-solving: If MIRA visited your community (even if you’re far from the ocean), what “mission” might they take on to protect nature nearby?
  8. Global connections: The book references places and stories from the Asia-Pacific region. Why is it important to read stories that include cultures and locations from around the world?

ACTIVITIES

Science (ocean conservation and simple research)

1) “Save the Sea Creature” mini-poster

  • Students choose one animal from the story (manta ray, seahorse, whale shark, etc).
  • Include: habitat, what threatens it, and 3 ways people can help.
  • Add a labeled illustration and 3 vocabulary words from the glossary.

2) Coral Bleaching Demo (kid-friendly model)

  • Use white paper coral outlines or pipe cleaners as “coral.”
  • Discuss what reefs need to stay healthy (clean water, stable temperatures).
  • Students write: “Coral reefs are important because…” and one action humans can take.

3) Plastic Audit Challenge

  • Track classroom/home plastic for one day (wrappers, bottles, bags).
  • Make a class chart, then set a one-week goal to reduce or reuse.

Geography (Place-based learning)

4) Map the Mission

  • On a map of Asia, students locate and label places mentioned in the story.
  • Add compass directions: “From ____ to ____ is (north/south/east/west of).”

5) Ocean Connections

  • Discuss: “How do oceans connect countries and people?”
  • Students draw arrows showing how pollution in one place can affect animals elsewhere.

Writing (SEL & Persuasive writing)

6) Letter to Pirate Polymer (persuasive writing)
Students write a friendly but firm letter that includes:

  • What he did (specific examples)
  • Why it matters (effects on animals)
  • 3 actions he should take to help
  • A hopeful closing line about being part of the solution

7) “MIRA Mission Report” (informational writing)
A one-page report with headings:

  • Mission Location
  • Problem Discovered
  • Evidence
  • Solution Plan
  • How Humans Can Help

8) Ocean Promise Wall: Each student writes one sentence starter:

  • “I can help the ocean by…”
  • “I learned that marine animals need…”

Post them on a bulletin board or mural.
