Frogs are amphibians in the order of Anura (meaning "tailless"), and unlike other amphibians (salamanders, caecilians), frogs lack a tail in their adult form, (but that's up to one's imagination whether they'd like to draw them a tail or not) Unlike reptiles, these amphibians lack scales but instead they have a permeable skin covered in film (making it feel slimy and slippery), which the frog "breathes" through, receiving oxygen straight to their bloodstream, especially underwater. Therefore frogs are usually confined to a wet surrounding, such as swamps, ponds, lakes or such, but that's not always the case. A frog's usual prey would be invertebrates, but with a bit of imagination regular-sized frogs would devour faeries or other small creatures, or giant frogs devour bigger unwary prey from smaller mammals to somewhat larger (such as these careless biped creatures with limited abilities). They have a long, sticky tongue they shoot out with high speed and catch the prey with, which is drawn to the grip of their jaws to prevent escaping and the prey is finally swallowed, and digested in their simple digestive tract. So it all happens quite fast, so most of the thrill would be in escaping the predatory amphibian, although your chances are thin if you're not very good at swimming or jumping. But as frogs are at the bottom of the hierarchy - and the food chain - they usually become prey to larger predators.
There are many different kinds of frogs to come across, from poisonous colourful jungle frogs to big burly bull frogs. Licking a poisonous frog can cause different effects from intoxication to shrinking or changing shape or such. But never, ever eat a poisonous frog if you haven't developed a resistance against their unpredictable toxic.
