see those weird bumps on the toad’s head, right behind its eyes?
those are its poison glands. if you irritate the toad hard enough, it will ooze a disgusting toxin from those in the form of a poisonous foam!
and if you were to attempt to put the toad in your mouth at this point, you would get a mouthful of noxious ooze that could make you pretty seriously sick depending on what species of toad it was.
also it might pee on you, and who wants that? this is a lesson to humans and raccoons alike- leave that toad where you found it.
