There was an old mermaid who swallowed a shark. I don't know why she swallowed a shark, but it left no mark!

Scholastic's bestselling Old Lady is starring in a brand-new adventure series that will make you laugh AND learn! In this new spin-off, the Old Lady turns into an Old Mermaid, travels down into the ocean, and swallows a shark. . . and a squid, and a fish, and an eel, and a crab, and a sea star, and a clam. . . Why? Well, it was fun to cram her mouth with a clam!

Two new characters lead the reader through this hilarious adventure while exchanging some awesome facts about the creatures down under for a light take on nonfiction that's perfect for this age.
