Warcraft 3 Easter Egg - Elder Sasquatch

I think on the second level of the undead campaign, after you find out you need the urn for King Terenas's remains, if you go to the trees west of the green base you'll see some signposts with skulls. If you destroy the trees and them move into that area, you'll see a cut-out scene with two sasquatch, and Elder and a younger. after you kill them they drop a magic item.
