Frogs are mentioned in the How to Train Your Dragon Book series, but not actually seen.


Frogs (Order Anura) are amphibians who do not have a tail in their adult form, though larval stages - known as tadpoles - typically do have tails for swimming. Despite being bound to water or moist habitats, frogs occur worldwide with the exception of the Arctic, Antarctica, and true deserts. Though the greatest species diversity occurs along the equator in rain forests, frogs that live in cold and dry climates have many adaptions for survival. Many species are able to enter a suspended state of torpor or hibernation. During winter in many areas, frogs may enter hibernation in a burrow, in mud at the bottom of a pond, or under leaf litter. Other frogs can even be frozen, keeping vital organs from freezing by an excess accumulation of glucose. Some frog species in dry climates undergo aestivation (hibernation in hot weather) after burrowing into the earth and adapting physiologically.


In the Book series, frogs are mainly used as a derogatory descriptor for dragons. However, at least one human is referenced eating frogs.

In reality, the primary use of frogs is as a food source for humans. They are also used in medical research and medicine.


How to Train Your Dragon Frogs are mentioned multiple times, mainly for describing Toothless in a negative light.

Something that makes a Monstrous Nightmare look like a flying frog!
  Fishlegs hoping Hiccup grabbed a "cool" dragon from the Dragon Nursery  
What is it, Hiccup? A brown bunny rabbit with wings? A flower fairy? A fluffy flying frog?
  Snotlout describing Toothless  

How to Speak Dragonese

The Roman, Fat Consul, in How to Speak Dragonese eats a variety of things, including frogs, as listed on a detailed menu.

Gobber refers to Hiccup and Fishlegs as "tadpole poos" when he sees their boat sink and return without completing a 'Board-an-Enemy-Ship' lesson.

  — Book 3  

While is the custody of the Romans, Hiccup, Fishlegs, and Camicazi are served a variety of fare, including "pig stuffed with dormice stuffed with baby frogs carbonara and oysters fried in cream".

How to Cheat a Dragon's Curse

One Eye the Sabre-Tooth Driver Dragon compares Hiccup to a frog life stage.

Oh look, it talkssss ... The little Human tadpole is speaking the noble Dragon tongue ...
  — One Eye in Dragonese  

Then Snotlout mentions frogs when making fun of Toothless because he is wearing a winter coat.

'What is your ridiculous frogspawn of a reptile wearing?
  — Snotlout  

Later, the intense green color of Doomfang eyes is described in depth, relating them to the color of green frogs.

It was as if all the green in the world, of peas, of grass, of spinach, of leaves, of beans and frogs, had been concentrated in that one eye and given it the intensity of pure green acid.
  — Book 4  

Frogs are referenced again when Camicazi scales the wall surrounding Hysterical Village, "appearing to cling to it with invisible suction like a frog."

Toads are referenced when describing the speed at which a Doomfang's tongue can move: "as quick as a toad catching flies".
