Sacred Trees

 are interactive objects in Worm Food. They have some affiliation with the Witch Doctors. As the name says, they are sacred. They have a small green glow around them and green energy is seen surging up through them. When the Giant Worm goes up to one, its glow will push the Worm away. The Worm has to be fast to destroy it.
