Hahaha!!
Yes, they do.

Fun fact, @arrrados: the only reason people ever discovered truffles was because in the past, they noticed all the little holes next to some trees. Holes kept showing up during the night. First, people thought witches created them by casting spells in the forest at night.
So, they started night patrols. Only to discover it was the hogs digging up truffles, having some midnight snacks, LOL.
