When killed, most of the dinosaurs will drop a flashing P icon, and when it is collected, the suit will flash for a few seconds and the player can use a pulse rifle to destroy everything in their path. Vines and jump pads can be used to reach higher platforms. Regardless of what suit the player is wearing, it will change back to blue if they take enough hits. At the end of each cavern is a boss that needs to be defeated for Calvin to proceed to the next cavern.
