It's Mom and Dad's anniversary and Dad has bought Mom an extra special gift, a diamond ring. While Mom is out, George insists on helping to hide the gift. When trying to hide the ring in the bathroom medicine cabinet, the ring accidentally falls down the drain. So being the size he is, George goes down after it. It's a race to find the ring and get home before Mom does. And being the smart adventuring he is, George does just that and in the process finds lots of other treasure too.
