The April Fools Party 2024 is a party on Club Penguin Journey. It was released on April 1, 2024, and ended on April 8, 2024.
Nearly every room featured a unique and wacky design, referencing various other media. Some boxes in the Box Dimension were opened up, revealing even more dimensions. Rookie and Sensei visited during the party, with Sensei visiting under the alias 'Senslay'.
The Dance Club dance floor shows an animation of the video game Pac-Man. In addition, there are a couple of Rubik's Cubes to the upper left of the dance floor, and the Trollface in the back of the room just behind the DJ3K set, as well as another one right above the stairs to the Dance Lounge.
The Dojo is a reference to one of Toby Fox's games, Undertale. The room design is a reference to the room where the Annoying Dog resides. In the background, there is a gaming console that looks similar to both the Xbox One S and Xbox Series S, two video game consoles produced by Microsoft. There is also a Kinect device, used for the Xbox 360, both of which were also produced by Microsoft. Lastly, there is a banner that reads "Nah I'd win", which is a reference to a quote that Satoru Gojo makes in the manga Jujutsu Kaisen.
The Dojo Courtyard is also a reference to Undertale, with the same references above sans the background elements.
The Forest's computer background is a reference to Experimental Penguins, one of the prototypes for the original Club Penguin. In addition, the icons on screen, especially the taskbar, reference the Windows XP computer operating system.
The Gift Shop was designed entirely with ASCII Art.
The design of the Mine Shack was made in the video game Minecraft.
The Ninja Hideout is also a reference to Undertale, but is also a reference to Deltarune as well, which is another one of Toby Fox's games.
The Plaza's design is a reference to the Generation II Pokémon games, those being PokémonGold, Silver, and Crystal.
In the Ski village, the ground, path to the Ski Hill, and the background all reference the video game Geometry Dash. The background in particular references the infamous spider part of the level Dash, which was added in the version 2.2 update and subsequently became an internet meme shortly after its release.
The Snow Forts was built in the video game ROBLOX, specifically an early version of Roblox Studio, which is a client used to build, create, and develop experiences (formerly known as games) on the platform.
The Ice Rink is a photo of various toys from the Mix n' Match figures toyline of Club Penguin merchandise, including the Air Hockey playset, which is a replica of the Ice Rink.
The Town is a reference to Toontown Online, another Disney MMO. The Dance Club is the Minnie's Melodyland Toon HQ, the Gift Shop is a Gag Shop found in every playground, and the Coffee Shop represents the Toontown Bank in Toontown Central.
Interestingly, the Coffee Shop's exterior does not match the interior, where the walls are missing from both the main floor and the Book Room.
Some of the art depicting humans in the Town are in the same art style as the one used in the children's book/novel series Captain Underpants.
The Underground Pool shows a video of the 1928 animated short Steamboat Willie, which entered public domain on January 1, 2024.
The song that plays in PSA HQ is from the YouTube channel SiivaGunner. It can be listened to here.
