Help Tallulah the mermaid protect the Great Lakes--and learn how you can become an honorary mermaid too! Tallulah is ready to start her work as the Great Lakes' first official mermaid! After taking the pledge to protect and care for the lakes, she's off--caring for the various creatures that call the Great Lakes home, keeping the water and shores safe and clean, helping the boats navigate the waterways, and more! It's a big job. And when a raft carrying a pair of children gets swept from the beach into rough waters, she swims into action. Maya and Finn can barely believe they've been rescued by a mermaid! When the kids and Tallulah find they have a love for the Great Lakes in common, Tallulah makes them honorary Great Lakes Mermaids--she could use the help! She presents them with their own Petoskey stones and has them recite the Great Lakes Pledge. Backmatter includes information on how readers can become an honorary mermaid themselves!
