They're alive! They're also ready for action. After a long nap in the dry Arizona sand, hundreds of spadefoot toads reanimate on Sunday's new episode of "North America."
In a sneak peek that's exclusive to TODAY.com, narrator Tom Selleck likens the critters to Frankenstein's monster, only rousing after cracks of lightening get their attention.
The bolts and rumbles signal the start of the rainy days, which is a big incentive to wake up following 10 months without food or water. But as the groggy spadefoots surface, it's clear that sustenance isn't the only thing on their minds.
They soon begin to sing a distinctive, throaty song, and these frogs (spadefoot toads are actually a variety of fossorial frogs) don't sing to celebrate their love of a good tune. They have another agenda -- something Selleck calls "spadefoot speed dating."
In fact, once they hit the water, they go so fast that one "date" barely has time to end before a new partner wants in on the action. Male, female, couples, triples -- none of it seems to matter for the eager amphibians.
See what they get up to in the clip above, and see just how far they go when "North America" airs Sunday at 9 p.m. on Discovery.
