No one knows what it is only the moderators of Club Penguin and they change it daily so even if you did find out it would be either expired or would expire. So basically unless you are a Club Penguin moderator you won't be able to get onto that penguin. Unless you are a REALLY good hacker and know how to get past the fire walls.
To get the Gary stamp on club penguin, you have to be in the same room as Gary the gadget guy. Stamps like these can be really hard to get. To make it easier, you can use the Gary tracker found at the related link below.
