Club Penguin can actually be tough to beat however I encountered this accessible reference Club Penguin Mission Cheats guide that assisted me through my climb to the top levels of the game.
Club Penguin Mission Cheats are entered at the main menu. A verification message will appear when a cheat code is typed correctly.
In Cheat Mode, Start up your game and go to the screen that shows "Click to continue" or "Main menu". Club Penguin Mission Cheats can then be entered for the desired outcome.
You'll have to enter the cheats in blindly because there is no dialog box on display. If you input one cheats with mistakes, you are botching your opportunities typing any future codes. If you're certain you made a mistake typing the Club Penguin Mission Cheats, you'll have to restart the game for the cheats to work again.
