So, you are looking for some secret stuff eh? Well, for Club Penguin, this is the best place you will find!
1. To catch the mullet at Ice Fishing, you have to use a smaller yellow fish as bait for it.
2. To get to secret levels in Astro Barrier, wait on level 7 or the place between levels 30 and 31 and shoot a blue ship that comes by.
3. To have a puffle with no name just click space then the confirm key. Your puffle’s name will be !
4. To play Dessert Mode in Pizzatron 3000, click the small lever you see on the opening screen, before you click play. Warning: It is harder, but the amout of couins you get is doubled. And the idea of making a super chocolate pizza or the pink sugar supreme pizza is cool isnt it?
5. How to talk while reading the newspaper: To check, go as far left or right as you can. Go to the Aunt Artic Page then click the first option. Exit out of it. Then click Tab button (it might be nameless, but it has arrows on it) and type and you can say anything you want while reading the newspaper.
6. To stand on the exits (the place between areas), click on it, then click on your mail icon or newspaper. After about 10 seconds, exit that, and no one will be able to get you in tag!
Well, unfortunately, I could not put down more than that because I am sleepy and it is 4 in the morning.

mine is better
