operations manager tim faulkner has worked with this crocodile at the park since 2007. >> elvis has given me a hard time on a number of occasions. to a crocodile, the rumble of that mower, it's something that just turns them on. they have all of these sensitive receptors around their jaw, good hearing, eyesight. that rumble of the mower can trigger him. >> it triggers him all right. like the real elvis, this croc is interested in a little less conversation and a lot more action. >> a wheel got caught at the base of that tree which gave elvis that split second to grab it. and i went this way to about here and then started to come across, very slowly, happens a lot slower than you think. i said, let it go, let it go. the croc took the mower into the water. >> after wrestling the lawn mower away from the handler, elvis guards it. faulkner knows no man can match the strength of this 16-foot long beast. >> you have to pay credit to his strength. he lifted this mower up, and he just turns around. >> elvis doesn't take the mower because he's hungry. his motivation is slightly more egotistical. >
