Dream Land GB

Dream Land GB (, Pupupu Land GB), known as Dream Land (, Pupupu Land) in, is a stage in and Super Smash Bros. Ultimate, based off of Kirby's Dream Land.

In Ultimate, it is renamed to distinguish it from the similarly-named Smash 64 stage.

Stage layout
It is a transitioning and scrolling stage taking place in various areas of Kirby's Dream Land. As an added reference, all of the area's locales are rendered in an identical style to the original Game Boy's monochromatic screen; furthermore, the edges of the battlefield border resemble those of the Game Boy, complete with a red LED on the left border to show the life remaining in the Game Boy's batteries. When there are only five seconds remaining in timed matches, this light begins to dim, as if the Game Boy's batteries were dying out.

The stage begins with the original Game Boy boot screen with the scrolling Nintendo logo, then quickly transitions to the Green Greens phase. Periodically, the stage will randomly transition between seven different phases, three of which scroll right before transitioning to another phase.

If a player holds the L button while selecting the stage in, it will use a grayscale palette instead of green, mimicking later Game Boy models. This Easter egg is absent in Ultimate.

Phases

 * Green Greens: This section starts in a flat area with a door marked "In" in the background (this cannot be entered). After some time, a pointing hand appears and the stage scrolls right, passing over a pit and stopping at a cliff.
 * Castle Lololo (exterior): The exterior features two platforms on the bottom. The bottom-right platform has three small platforms above it.
 * Castle Lololo (interior): The interior has one bottom platform and three others arranged in a triangle. They are all hard platforms, so it can provide a cave of life.
 * Float Islands: This section starts at the end of an island, while a ship's hull is visible. Characters are not able to swim in the water, though the water will make a splash effect when entered. After some time, a pointing hand appears and the stage scrolls right, passing over the ship to a pair of small islands with 2 platforms on each (the edge of the ship is also on screen).
 * Bubbly Clouds: This section starts with four cloud platforms: two at the bottom and two at the top. After some time, a pointing hand appears and the stage scrolls right, stopping at three cloud platforms.
 * Mt. Dedede (lobby): The Boss Rush lobby has one bottom platform and two platforms on the left and right sides of the stage.
 * Mt. Dedede (boxing ring): The boxing ring is completely flat.

Ω forms and Battlefield form
In Super Smash Bros. for Nintendo 3DS, the Ω form is set in the Green Greens portion. It does not scroll and walk-off areas are absent. The "Game Boy" border is also not seen. Unlike its normal version, the stage appears in 3D. The grayscale variant can still be accessed.

In Super Smash Bros. Ultimate, the Ω form and Battlefield form use the background of the Green Greens portion, but the main platform resembles the wall design of the Castle Lololo exterior section. The platform is resized and reshaped to match and, respectively. The three soft platforms of the Battlefield form are small rectangles that are unique to this form. The characters are still flat, which also flattens the hitboxes and alters gameplay significantly as a result.

Hazards Off
No changes are made in Ultimate when hazards are deactivated; the stage still scrolls and the transitions to different phases still occur.

Glitches

 * A glitch can occur in the King Dedede's castle area of the stage causing the floor to "disappear". Players can randomly fall onto the lower blast line where it is impossible to get KO'd.
 * Another glitch can occur where one of 's Pikmin will become stuck below a platform that is not drop-through. The Pikmin will continue to be in its falling animation, but will still follow Olimar until he goes out from above the platform or until the stage shifts to a new section.

Origin
Kirby's Dream Land is the first game in the Kirby series, releasing on the original Game Boy in 1992 with five stages. Known for its short length and simplicity, and an outlier in the wider franchise for not featuring Kirby's iconic Copy Abilities introduced in Kirby's Adventure, players controlled Kirby as he traveled through Dream Land, picking up food, Superspicy Curry, Maxim Tomatoes, and 1-Ups. The five stages were Green Greens, Castle Lololo, Float Islands, Bubbly Clouds, and Mt. Dedede. Mt. Dedede was the last stage, effectively a boss rush before facing King Dedede, and upon clearing it, players were given the option to begin again in a more difficult "Extra Game". Certain platform layouts are copied from level layouts from the original game, most notably the boss gates in Castle Dedede, the arena where Lololo and Lalala are fought in Castle Lololo, and the cliff where Kirby rides his first Warp Star in Green Greens.

The hand that occasionally appears to indicate scrolling is based on the gloved hand that appears on the Game Over screen of the game, both acting as the cursor for the choices and coming to life to either wake Kirby up to continue or flicking him off the screen should the player decline to continue. This hand reappears throughout the series to serve the same role in Game Over screens.

Dream Land GB uses a frame based on the original model of the Game Boy, which featured a green, monochromatic screen with an adjustable brightness. The stage accurately reproduces the Game Boy's display at medium brightness, including the red battery light and "DOT MATRIX WITH STEREO SOUND" text. In, the stage can also be displayed in shades of gray, which resembles later models of the Game Boy, such as the Game Boy Pocket and Game Boy Light, as well as a color scheme option provided when playing classic Game Boy games on the Game Boy Color, Game Boy Advance, Super Game Boy, or 3DS Virtual Console - the frame does not change to match any of the prior 4 platforms when playing on gray mode, making it instead resemble the digital Game Boy borders from the latter 2. The gray color scheme also makes the stage resemble the final platforming level of Kirby's Adventure, a throwback to Kirby's Dream Land and one of the earliest examples of a video game intentionally replicating the aesthetic of weaker hardware, a stylistic choice which has become a staple of the Smash franchise, influencing stages such as Dream Land GB, Pac-Maze, Mute City SNES, and the returning iterations of Smash 64 stages.

Tournament Legality
In both games, Dream Land GB is banned due to its side-scrolling walk-off blast zones and the character's flattened hitboxes, which significantly affects gameplay as a result. The Battlefield and Ω forms of this stage are also banned due to the aforementioned flattened hitboxes.

Trivia

 * The pic of the day from August 8, 2014 that features the monochrome and  costumes further references Kirby's Dream Land, as the game had monochromatic graphics on the Game Boy. The reveal took place before it was revealed that the stage was -themed.
 * Additionally, the Miiverse caption for the aforementioned picture references the Game Boy start-up sequence jingle.
 * Due to the close proximity of the background, no Star KOs occur in this stage; only standard KO blasts and Screen KOs occur. This also applies to its Ω form.
 * This stage was originally conceived as being based upon , but the concept instead became Dream Land.
 * In the Float Islands section, some of the cliff-sides are improperly layered, always being layered in front of the platforms above them, even when seen from above. This can clearly be seen in Angled Smash.
 * The grayscale version of this stage and Mushroomy Kingdom's World 1-2 variant are the only differently loaded versions of stages not in Super Smash Bros. Ultimate.
 * In Ultimate, the following Assist Trophies cannot appear on this stage: Thwomp, Color TV-Game 15, Yuri Kozukata, the Squid Sisters, the Ghosts and Shadow the Hedgehog. The Moon, Nightmare, Andross, Devil, and Dr. Wright cannot be summoned on this stage at all. Additionally, the following Poké Ball Pokémon cannot be summoned: Alolan Exeggutor, Lugia. Kyogre, Palkia, Giratina, Arceus, Zoroark, Kyurem, Xerneas and Lunala. Abra can only be summoned on the stage's Battlefield and Omega forms.
 * picks up sand blocks instead of dirt blocks on this stage.
