Yeah, some pacmans love and use their water dishes all the time and others don't use them at all. Grif hardly ever uses his. I think some of that has to do with how moist you keep their substrate too. I guess as long as its deep enough for them to completely bury themselves and its kept pretty damp then they don't need to use actual water to cool off or drink because the obsorb the water they need from the soil. Grif gets his water from the soil. Sometimes when he unburies himself he's huge because he soaked up a bunch of water from his soil.
