Pebblet, a cute mob for the lifeless caves

Pebblet would be an adorable creature that inhabits the dripstone caves. It would be a small, armless stone creature similar in shape to a strider. It would also have big eyes and be made of stone. As for the use for it, perhaps it would have a very small chance of dropping ores, meaning players could create a functional ore farm! ( Note: the drop chance would have to be very low so that players won't stop mining.
