Toad
Frogs & toads mostly differ in their portrayals in fairy tales. If you kiss a frog you can turn him into a prince, whereas kissing a toad would result in warts appearing all over your body!
Perhaps this is because the skin of a toad is drier & has a warty appearance. Whereas the skin of a frog, is moister and smooth. Did you know toads also have the ability to breathe through their skins?
