You'd feel a slight sting as the gecko's teeth cut into flesh, but as soon as the blade of your axe left the gecko's skull, the beast fell to the ground twitching. It would spasm there for the rest of it's very short life, dying in about twelve or so seconds. That left the last lizard, the one you had stunned with your rifle, who continued to run and lunge right at you. Despite being so small and physically puny, these creatures were physically capable of rather impressive levels of athleticism, not just their climbing ability but also leaping. This is most important because the last gecko jumped high enough that it was going to try and bite your face.
