After later fleeing into a cave, the group held at bay a Hanonian land eel by throwing spears, and Tuvok shooting arrows, at the creature, but only briefly; upon exiting from the cave, Tuvok, Chakotay and Kim collapsed the entrance by prying loose rocks from the roof of the cave, using their spears for reach and leverage.
