You thought you had the best luck. You thought you could just sit back and watch this Giantess's feet without her knowing. I bet you were really enjoying just being invisible to her. Imagining what those giant feet could do... But, she has an excellent sense of smell, and she thinks you stink, even more than the clouds of smoke she is polluting the town with. But, that does not mean she won't eat you. Once she finds you she is excited. There is nothing that makes her happier than swallowing silly little men.
