Maybe he was after some nuts?
(Was on QI a bit ago about some type of nut that is best eaten when passed through an elephant, think I'll stick with peanuts tbh)
Just what were you looking for to find that?
Found this on QI forum:
“Manketti nut, or mugongo nut (Ricinodendron rautanenii) is borne by trees growing in tropical Africa. The nuts are about the size of a hazelnut but resembles cashews. The nutritious kernels can be eaten raw or roasted. The raw fruit pulp tastes like dates but less sweet, and, when boiled down, turns maroon in colour and tastes like apple sauce. What makes this nut so remarkable, and may diminish its appeal, is the fact that it is usually gathered from elephant dung. Elephants are good at picking the fruit and greedily eating it, but their digestive systems cannot utilize the very hard nuts. Therefore, when these nuts emerge about a week later, they are ready to germinate. People then collect, clean, crack, and eat the nuts.”
