Your freedom. Which, is quite easily more valuable then anything you have in this cave wouldn't you agree? You let us go and fight Gaster. If we lose, simply say that we snuck in while you were out hunting for food, or while you slept. You end up avoiding having to hunt us down and kill us, while I constantly insult you as you try to do so, and you suffer no consequences. While if we WIN, well then you get freedom. No more having to take orders from some eldritch being that bosses you around. No matter what, it's a win win for you. Nothing to lose, everything to gain.
