Back to That One Achievement
Club Penguin had hundreds of stamps in its lifetime. Earning all the stamps for a game would double the amount of coins you earned by playing it, but you'll have to work very hard for that.
- Squid Spotter for Aqua Grabber. This is an Easy stamp, and all you have to do is go down to the middle of Clam Waters and see the squid. The problem is that getting the squid to appear is a Luck-Based Mission, as it has a very low chance to spawn every time you play.
- The unofficial rerelease Club Penguin Rewritten adds a similar achievement for catching the rare mullet. It's caught the same way as the regular mullet, feeding it a fish, but it only has a 1% chance of spawning instead of the regular mullet.
- Also for Aqua Grabber is Soda Pressure. To get this stamp, you have to complete Soda Seas's Compressed Air Mode without losing a life. Compressed Air Mode turns you into a Fragile Speedster, who can move insanely fast (which is not helpful when navigating the many tight passages in the level) and dies after touching a wall or obstacle.
- Astro30 Max for Astro-Barrier requires you to beat the first 30 levels without missing any shots. Ridiculous timing and precision skills are needed.
- Match Master for Card-Jitsu was affected by a bug that made it so you had to complete 25 matches in a single play session. Thankfully, this was fixed to be 25 matches in total, which is much more manageable.
- The Sensei Card stamp for Card-Jitsu is another Luck-Based Mission. You have to see the rare Sensei card in play, but there's no guarantee that you'll ever run into it while getting your belts. Just play matches and hope you see it.
- The Survivor stamp in the Catchin' Waves minigame, requires beating Survival mode. It consists of dodging ice chunks, outsurfing a fast wave, and a Threatening Shark near the end, its own Extreme Stamp for getting that far! On top of that, the whole thing takes over 10 minutes to complete, meaning that you'd better have a few spare hours in your schedule if you plan to try this, and God forbid you wipe out after the halfway point!
- Jet Pack Adventure's Puffle Plus stamp is incredibly difficult. You have to rely on the jerky movements of a Green Puffle to collect 450 coins for you. No, you can't just collect the coins yourself, the puffle has to touch them.
- Also for Jet Pack Adventure is Ace Pilot. If you don't collect any coins, including depleting your fuel before landing on the goal so you don't get bonus coins, you get this stamp and a 1000 coin bonus. While the first three levels are okay, the narrow cave levels have coin placement that's difficult to avoid.
- The Pizza Master and Dessert Chef stamps for Pizzatron 3000 require you to make all 40 pizzas perfectly. Pizzatron relies on Difficulty by Acceleration, and the last 15 or so pizzas are brutal to make in time.
- Smoothie Smash isn't the hardest game, but Smoothie Master requires you to survive eight minutes in Survival mode. Good luck dodging obstacles and not running out of lives for that long.
- Ice Master for Thin Ice requires you to complete all the mazes perfectly. In the later, more complicated mazes, this gets insanely hard without a walkthrough.
- The Mascot stamps are often difficult to get, as you have to be lucky enough to see the mascot in the first place. They only visit for certain parties, and while it's not had to figure out which party a mascot will visit, finding them is difficult. While they did start posting meetup times around 2012, good luck getting in the server and wedging your way into a full room to get the stamp.
- Luckily there was Developer's Foresight for this. Mascots would very rarely use the map, instead waddling between rooms, and so normally if a mascot was within a dead end room you could wait outside for them to come out.
- Many Party stamps could only be obtained once per year, if not less frequently. For example, the Out At Sea stamp could only be obtained twice in the history of the game, with Mountaineer being available exactly once.
- It's very hard to get the specific outfit stamps (Ninja Meeting, Soccer Team, Hockey Team, Tree Mob, Berg Drill, Floor Filler) without searching for a group planning to do them. The igloo stamps take this up a notch, as you're required to have 30 penguins at once in your igloo. Good luck finding 30 people willing to log on at the same time and sit around in your igloo.
- Needless to say, all three of the Insanity Stamps from Rewritten were ridiculous to unlock.
- The easiest one was the Rare Mullet Stamp, which required the player to spot the rare mullet while playing Ice Fishing. What made this one near impossible is that there was only a one percent chance the rare mullet would appear and the player won't know they've found it until they would have the chance to catch it.
- The second is the Unbeatable Stamp, which entailed the player getting 25,000 points in Cart Surfer's Hardcore mode. Cart Surfer is already regarded as one of the more difficult games in Club Penguin, so having to last that long on the game's hard mode was no easy feat.
- Finally, the Pure Ice! Stamp, which could only be gotten if the player earned an A grade on any extreme dance track in Dance Contest. Considering how all of the buttons are randomized on extreme in dance track, it boils down to the player having insanely fast reflexes or just getting very lucky.
