The main story is peppered with curious encyclopedic asides both about elements of Marcel's memories, from music to technology, and about elephants themselves – we learn that an elephant sleeps very little at night, "usually standing, always on alert," and takes standing naps throughout the day; that an adult elephant needs to drink 30 gallons of water a day and eat between 220 and 440 pounds of food depending on the season; that an elephant can't jump and must have one foot on the ground at all times; that despite an enormous weight of about five tons, an elephant makes no noise while walking.
(The information in the children's book, unlike the video trailer, is 100% accurate)
