The turtles are Archaean creatures. Their thick shell covered with spikes protects their skeletal bodies. They typically ignore lesser creatures such as Trilobites, but when encountering a creature they consider a threat they retract into their shells and eject a volley of deadly spikes. Both their spikes and themselves deal a third of a bar of damage. The spikes damage Rusty, other enemies (and the Turtle that shot the spikes, assuming the spikes don't go far enough away), and tiles.
