Step 1 : Introduction to the question "Because they mainly eat eucalyptus leaves, which animal is often said to smell like cough drops?"
...Koalas are famous for feeding almost exclusively on eucalyptus leaves, which contain aromatic oils used in cough drops and medicinal products. Because of this diet, koalas are often described as having a pleasant eucalyptus or menthol-like scent. Their specialized digestive systems allow them to process the toxic compounds found in eucalyptus leaves, which most animals cannot safely consume. Koalas can eat more than a pound of eucalyptus leaves each day and spend much of their time sleeping to conserve energy from their low-calorie diet.
