The game got an MSX-only sequel called Penguin Adventure in 1986, which is also known for being supposedly the first game Hideo Kojima worked on while being employed by Konami. Another sequel was released titled Yume Penguin Monogatari in 1991 for the Famicom.
Both games contain examples of the following tropes:
- Alliterative Title
- Anti Poop-Socking: The criteria for the gold ending in Penguin Adventure requires you to pause the game a certain number of times during a single playthrough.
- Downer Ending: Fail to meet the criteria for the good ending in Penguin Adventure and the Penguin Princess will die before Penta can get the golden apple to her.
- Edible Collectible: The penguin can eat the fish that jump out of holes for 300 points each. Averted in the sequel Penguin Adventure, where fish are used as currency instead.
- Endless Game: After stage 10, the game starts in the first level again but with added obstacles.
- Everything's Better with Penguins: The protagonist is a penguin, and he is named Penta in Penguin Adventure.
- Game-Breaking Bug: The Famicom release of the game will not work properly if you have your Zapper (or indeed, just about anything else) hooked up to the expansion port of the Famicom, with Penta locked at a rather low speed. This means you'll need to deal with the bother of unplugging your Famicom BASIC Keyboard or Zapper each time you want to play this game, and plugging them back after.
- Guide Dang It!: The criteria for getting the good ending in Penguin Adventure is not hinted anywhere in the game.
- Public Domain Soundtrack: "The Skaters' Waltz" composed in 1882 by Émile Waldteufel. It loops over and over again on every level.
- Scoring Points: Points are gained by grabbing flags, fish and jumping over holes.
- Slippy-Slidey Ice World: Takes place in the South Pole, with every level being ice levels.
- Super Speed: As Weird Video Games pointed out, if you work out Penta's speed from the distance meter, he travels at Mach 58!
- Timed Mission: On Level 1 you have to travel 900 km in 70 seconds note , on Level 2 you have to travel 1,100 km in 90 seconds and so on, with various time, distances, and amount of turns and obstacles.
