in the HQ
ski lodge
You go back to HQ and ask G, He gives you a flashlight.
Gary gives you a flashlight its on a table to your far right
Well you go to the Boiler room with your flashlight *wink wink* and you'll see a silver thingy or whatever but anyways you click on it, it opens and you have to solve a puzzle. If you can't figure out what I'm saying go on youtube and type in "clubpenguin how to solve the case of the missing coins".
You can play the Case of the Missing Coins by going to the HQ and clicking on the green screen icon in the lower left hand corner then clicking on the Case of the Missing Coins.
Find the coins.
