I wouldn't get too worked up about it if your chlorine level is where it should be and the mole had not been in there more than 24 hours or so. If you're worried you can shock using the Pool School instructions.
IF your FC and CC are within range I would not worry about shocking. I find moles, frogs and other small critters in my skimmer from time to time and unless I have neglected to check the skimmer for days it has not been an issue. It's when they sit in there for days that I pay the price and have to shock.
If it makes you feel better raise the pool to shock level overnight, mustard shock level if you are really anxious. "Triple shock level" is crazy. Usually you only need to shock if serious decomposition has set in before discovery.
