Salary

Starting May 1st, 2009, penguins who were Secret Agents and/or Tour Guides began to receive 250 coins per job each month for doing their "jobs". Their salaries are paid through Penguin Mail. This information was first confirmed by Billybob, and later by The Club Penguin Times (found in issue #184).

Trivia

The cards that Penguins get when paid.

If a penguin is both a Tour Guide and a Secret Agent, they receive a total of 500 coins a month.
Even if a penguin has no activity whatsoever of their job, they will still get paid.
It is possible to earn 3000 coins per salary in total if the salaries are saved for a whole year, meaning if a penguin has two "jobs," a total of 6000 coins would be saved.
It is possible that Jet Pack Guy is the Agent on the Secret Agents salary postcard.
It is possible that the Tour Guide on the Tour Guide's salary postcard is the same penguin that is on the Club Penguin site's homepage.
