Chest Turtle - A herbivorous, massive, and terrestrial descendant of box turtles. 2. Forage Skink - An omnivorous, sizable, and semi-arboreal descendant of broadheads. 3. Sand Worm - A fossorial, large, and predatory descendant of eastern glass lizards. 4. Terragator - A carnivorous, smaller, and terrestrial descendant of American alligators. 5.
