Many frogs have a mild toxic substance in their skin that serves as a defense to potential predators.

Most frogs and toads have large poison glands located on the sides of their heads and elsewhere on their bodies that secrete mucus and a variety of other toxins that make their skin slippery to hold, distasteful or poisonous.  Some frogs, such as the poison dart frogs, are especially toxic.
