The Director will ask you if you want to become an EPF agent. Click yes, and The Director will give you your Spy Phone. You're now officially an EPF agent! You can get to EPF HQ either by teleporting there with your Spy Phone.
Or clicking on the waterfall at the back of the Everyday Phoning Facility.
Your duty as an EPF agent is to protect the island of Club Penguin. So remember... Be resourceful, be remarkable and be ready.
