‘Please Don’t Lick Psychedelic Toads,’ Says National Park Service.

We didn’t even know this was a thing.

Apparently, visitors to the National Parks have been tracking down the Sonoran Desert toads — and licking them.

No, this isn’t some Disney Prince tale gone array. These peculiar toads release a psychedelic as part of their defense system.

These toads, also known as Colorado River toads, “have prominent parotoid glands that secrete a potent toxin,” the Park Service advised. “It can make you sick if you handle the frog or get the poison in your mouth,” it warned.

“As we say with most things you come across in a national park, whether it be a banana slug, unfamiliar mushroom, or a large toad with glowing eyes in the dead of night, please refrain from licking.”
