Crappo

Medical attention is immediately needed if "Fido" encounters a specie of huge toad, up to eight to ten inches round, called a "crappo", and decides to take it into his mouth to play with. This toad exudes a substance from glands in its skin which will cause profuse salivation, and sometimes, if absorbed, will cause the animal to become very excited with high fever and twitching uncontrollable motions.

One of the wild animals most familiar to all Trinidadians, even those with not the slightest interest in wildlife, is the crappo, that large toad which is seen so often at this time of year around houses and roads.

Little crappos would find their way into the house. I was tormented by them. When in panic I feared they, like fluttering pigeons, were liable to do anything.
