A Pisadeira.

Legend has it that the treader appears hideously on top of people who eat too much. In addition, she always appears when there is exaggeration and food is not shared with those who are hungry. It's like the sin of gluttony: "Anyone who eats and doesn't share anything gets a bloated belly", as Seu Madruga used to say. And we add: with a swollen belly, the treadmill comes and empties it.
