The Foreign Language Phrase Book is an item from Freddi Fish 3: The Case of the Stolen Conch Shell.
The phrase book is first seen being for sale on Sam the pelican's island. Freddi Fish and Luther gets the book after selling the Orange Sea Urchin to Sam. They later use it to translate the language Horst Fedders the Seahorse is speaking. Then they ask him if they can have the Shim-Sham-Jimmety-Jam-Clapper-Gapper that's in his bag, which he gladly gives them. When Horst confesses he is the thief who stole the conch shell, he uses the book to translate his language.
