Where is the secreat room in Club Penguin?

Answer 1

There are multiple secret rooms. The most common is the PSA hideout (located in the Sport Shop), where you can do missions. You test in by clicking the "M" at the top of your player screen. There is also an EPF hideout, located within the PSA hideout which you unlock by uploading coins onto your account from the EPF game on the Nintendo DS. The last hidden room is the Ninja hideout which you unlock by becomiong a Ninja (play Card-Jitsu until you get your black belt, then challenge Sensei and win). If you are a member, there is also the Fire Dojo.
