A great gift for your granddaughter who loves amphibians would be a terrarium or vivarium where she can keep her own pet amphibian! You can also consider getting her a book on amphibians, like "Amphibians: The World of Frogs, Toads, Salamanders and Newts" by James H. Harding, or a stuffed animal shaped like her favorite amphibian. Another option is a biology kit that contains materials for dissecting a frog or a salamander, or an adventure book about a character who loves amphibians.
Or you can get her a star map with the date when she was born.
