Penguin Land, known in Japan as Doki Doki Penguin Land: Uchuu Daibouken (どきどき ペンギンランド 宇宙大冒険), is a Sega Master System puzzle platforming game developed by Sega R&D 2 and published by Sega. First released in Japan in August 1987, it was later brought to the United States and Europe in early 1988, making it the only entry in the Doki Doki Penguin Land series to be released internationally.

The direct sequel to the 1985 Sega SG-1000 game Doki Doki Penguin Land, the game evolves on the previous entry by introducing more block types, enemies, and level layouts and including a level editor.

The Japanese version's subtitle "Uchuu Daibouken" means "Space Adventure."


Penguin Land SMS, Introduction.png


Three penguin eggs are lost on a distant planet. Penguin Mission Commander Overbite must guide these eggs down to the bottom of a frigid cavern filled with traps, enemies, and secret passages to rescue them and carry them to safety.

The game is a platforming game where the player controls a penguin named Adelie (アデリー) in the Japanese version or Overbite in the Western versions. The goal of each round is to successfully push and drop an egg down a cavern of ice. Overbite can push the egg left and right, push it off cliffs onto lower platforms, and melt ice blocks to create a passage for the egg, avoiding polar bears, rocks, and other hazards. The round is completed when the egg is successfully delivered to the "Spaceship Crew" (ペンギンの 子どもたち) under the lowest platform of the level. There are 50 rounds; the first 30 rounds can be selected in any order, and clearing them all unlocks the last 20 rounds.

Overbite moves with Left and Right and jumps with 1. Walking into the egg rolls it in same direction. Jumping on the egg rolls it out of the way in the opposite direction. Overbite can break the platform in front of him with 2, which melts a hole through the ice that he and the egg can go through. Levels scroll vertically, but the screen only scrolls when the egg is moved; if the egg is not moved to force the screen to scroll, Overbite can fall through the bottom of the screen and reappear at the top. When the game is paused with  PAUSE , the level layout can be panned downward with Down; the game unpauses when the player pans to the bottom of the level.

If the egg falls more than three blocks downward, it breaks. A blinking bar under the egg shows this distance. If Overbite lands on the egg but there is no room for it to roll left or right, it breaks. The round must be restarted if the egg breaks (and the game ends if the player runs out of eggs). Overbite is knocked out if touched by an enemy or hazard but recovers after a moment without needing to restart the round. There is a timer (starting at 99 seconds for each round), but it only provides bonus points at the end of the round for the amount of time remaining; the round does not end if time expires.

Ice Block
These blocks make up the majority of the platforms in the game. Overbite can melt them with 2 when standing on an adjacent block. They are the only blocks that can be melted.

Gangow (ゲンゴウ)
Polar bears that attack both Overbite and the egg when they are nearby. If they back the egg into a corner or land on the egg, it breaks. Rocks can be dropped on or pushed into them to crush them.
Penguin Land SMS, Enemies.png
Cameel (カミール)
Birds that fly across the screen if the egg is not moved after a set time. They drop bricks that can crack the egg.
Penguin Land SMS, Enemies.png
Some blocks contain ghosts that invert the player's directional controls for the rest of the round if they catch Overbite. Overbite wears sunglasses and smokes a cigarette while this effect is active.

Penguin Land SMS, Level Editor.png

Level editor

The game includes a level editor that can save up to 15 user-made levels to the cartridge's battery backup.

The level is a grid of tiles. The player can move the cursor across the grid using the D-Pad. Pressing 2 toggles a menu that allows the player to select an object to place. Pressing 1 places the selected object at the cursor's current location. The player can hold the D-Pad in a direction while holding 1 to place multiple objects.

The level is divided into two halves (with the second half accessed by scrolling through the bottom of the first half).
