e. Earthworm
Find a place where you have seen earthworms in the past, preferably where the dirt is bare (i.e., no grass). Soak the area with water to drive the worms out of the ground. Worms need air, so when it rains (or when a Pathfinder soaks the ground with a hose), they will come to the surface. They might not come out immediately, so you should plan to return a day later to look for tracks in the mud you've made.
