Biggest CP cheats

To enter expert levels in Astro Barrier, wait 30 seconds between level 30 and 31 and shoot the blue ship that appears.
Astro Barrier Cheats: On level 7, when the screen tells you about the blue bars/enemies, click the one in the example for a free life. On level 10 or 30, if you wait a minute, a blue ship will appear, and if you shoot it, you’ll go to the expert levels.
To catch the Big Fish in Ice Fishing, use a little fish as bait!
At the menu of AstroBarrier (the screen you get to after you press the Start Button), press 1, 2, or 3, to get to level 10, 20, or 30!
Puffle with no name: Buy a puffle at the store, when you’re asked to write a name, just push the spacebar a few times, then click Next.
Low definition Club Penguin: This is good if you’re in a laggy server. Press the += button next to the Backspace button to go to Low-def CP mode. You won’t lag anymore!
Sitting Forward: Press a spot to walk to (You can face anyway you want [forward, sideways, backwards]). Press s.
I don’t believe this is really a cheat but your puffle dances along with you when you dance (That is assuming you are taking it out for a walk).
Hidden buddies: If any of your buddies are logged in in a different server than you and you log in, check the buddy chat quickly after you log into any server (other than the one your buddy is on) and your buddy list will say they are on (even though its only suppose to say that if they’re on the same server as you [By server I mean like 'Tundra' or 'Mammoth']). You will only see this for one to two seconds.
To play Dessert mode in Pizzatron 3000, click on the lever when you’re at the start menu.
To put wall items flipped sideways, have a wall item up on the wall and quickly drag it outside the igloo, and it should be sideways.
WEIRD DANCE WITH DIFFERENT CLOTHES ON: Have on any clothes (something cool), open your player card, take off everything and put on an item that makes you do a special dance or wave (like Maracas or a tour guide hat). With the player card still open, do the dance/wave, and you should be dancing with the other clothes on! Once, I had been throwing snowballs prior to this and each time I waved with the tour guide hat on, my penguin with the clothes on would throw a snowball and hold the sign up at same time.
To make furniture items go on the wall and vice versa, double click the furniture item on the top rows of your inventory. You can do the same with wall items.
WALK ON LIGHTHOUSE WALLS: Go to the lighthouse, go behind the barrel of fish (or somewhere between the barrel and boat), click the door a few times and then click above the door, and you’ll walk on the walls.
DANCE AND TALK WITH THE PAPER: Update: (Doesn’t work anymore. I’m keeping it up here because this was an awesome glitch. ~Watex) Unfortunately, this cheat does not work anymore. However, you can still spy on friends when you’re reading the newspaper and type into the chat box. Walk to the bottom of the screen so you’re above the chat box in Club Penguin. Open the newspaper and start to send a joke or riddle. When it asks what you want to send, press tab until you can type into the chat box. If penguins next to you talk to you, you can see what they say.
NUBBING: To nub (walk behind your chatbox at bottom of screen), go to this site (or it won’t work if you don’t): http://play.clubpenguin.com/load.swf, then press f11, and click on the white space below your chatbox (the chatbox is the place where you type in words to say).
FLASHING WORDS: Say “green commander of (you can say anything here)” and the words will flash (excluding the parenthesis, what I said inside the parenthesis, and the apostrophes (these things: “). For example, green commander of mhd will flash if you say it. It works best if the word you use is 3-5 letters long.
Flashing words 2: Type with CAPS LOCK ON this: I saw a monster in a box So it should come up like this on Club Penguin: I SAW A MONSTER IN A BOX (Im leaving spaces to signify no period). Then just walk around and the words will flash (as long as the chat you typed is still there; yes it can go away if you don’t walk for a while) . Another flashing words cheat is “People how do you work the blender?”
You can log onto any mod’s account including Rockhopper’s on the Club Penguin Big Screen mode by typing their username and a random password, however, you will get banned immediately if you aren’t using the mod’s IP Address (their computer). (This means you can only long in without getting banned if you are using the mod’s PERSONAL computer)
If you can beat ‘Jet Pack Adventure’ without getting a single coin, you will get 1,000 coins at the end as your reward.
MORE FLASHING WORDS: Say “Green commander of cheese” without the quotes and move around and it will flash!
You can get the Rainbow Bracelet at the end of ‘Rockhopper and the Stowaway’s book on the last page. You can find the book in the room above the Coffee Shop.
Surfing Game cheat: Bring your RED puffle with you when you play the surfing game and it will surf along with you.
If you look in the binoculars in the Cove, and wait 10 seconds, you’ll see a speedboat whiz by with a penguin clinging on with a Tube.
Look like you’re holding the ‘Tours here’ sign, but with no sign: Wear anything (it works best if you’re wearing nothing though), then open your player card, and take off everything in your player card and put on your tour guide hat, BUT DONT CLOSE YOUR PLAYER CARD. Now, with your player card still open, wave. You will be holding up your hands!
Sliding even when not on the Ice Rink: As long as you’re on the Ice Rink room, you can still slide even if you’re not on the actual ice! For example, you can slide on the stands of the Ice Rink.
How to spam: Spamming is talking nonsense real fast. To spam, press j repeatedly real fast and you’ll be telling jokes at the speed of light (If you’re not telling jokes, try moving to a different spot and/or make sure you’re not typing into the chatbox)!
Hidden emotes: Coin emote: Press E and then M; Star Smiley: Press E and then N; Igloo emote: Press E and then I; Music note emote (also makes a farting noise): Press E and then T; Pizza emote: Press E and then Z. There are other emotes you can display by using this method that are already on your toolbar (Heart, Skull symbol, flowers, clover…) that you can find yourself by just testing it out. And if these aren’t working for you, try moving to a different spot on the screen.
Have over 100 buddies: When you have buddies in the 90s (I suggest having 99 buddies for this cheat to work), ask as many people as you can or want to be your buddy and DONT OPEN THE MAIL TO SEE IF THEY ACCEPTED OR DECLINED, just keep asking more and more people. When you think you’ve asked enough people, open all the buddy replies, and even if more penguins accepted so that you’d have more than 100 penguins, they’ll still be your buddies and you’ll have over 100 buddies.
How to shoot snowballs really fast: Rather than pressing the snowball button on the chatbar in Club Penguin, just push T on your keyboard. So just keep pushing T and clicking to fire and you’ll be shooting real fast!

Wow awesome cheats!I knew most of them already but they really good.
