I'm having trouble of my own with the magic hole. I don't have any problems finding it, but I can't figure out how to get anything out of it besides a rock. Does it need a special combination of numbers of items, or is it counting up to a certain total? Or is it random?
For example, I'm assuming I need to put apples and bottles in at the same time to get apple juice. Does it want, say, exactly two apples and three bottles, or does it want me to keep giving it apples and bottles until I've given it a total of three hundred of each?
