Bobby Cowan and his two friends visited his ranch to adjust a windmill, but while they were on the property, they saw something slither below the old, abandoned cabin. Who wants a rattlesnake slithering across their property? No one. No one does. So they decided to lift the cabin to find the rattlesnake. When they looked below the cabin, they discovered something shocking—you could even say it was unnerving or rattling. As soon as they lifted the shed, they dropped it back on the ground. They couldn’t believe their eyes. But they dared to lift it again for filming purposes—the video ended up going viral, too. Can you guess what was under his cabin? You may be able to guess what was there, but the total number will shock you—and maybe gross you out. Find out what Bobby discovered under his forgotten shed in our video!
