The player character, called Sierra Sam, is enjoying their life in the real world until the Call to Adventure beckons. The fantasy world of Greene is slowly dying because of the evil Bio-Haz, who's polluting the realm to empower his army, and it's up to Sam to stop him before all is lost. Along the way Sam meets several other characters, who are all named after food for some reason. With a land in peril, it's up to you to stop the pollution at its source and save Greene's lush environments.
This game contains examples of:
- All There in the Manual: The player's name is decided by the player in-game but is Sierra Sam on the back of the game box. Similarly, Bio-Haz's full name is Biohazard Harry in the manual.
- American Kirby Is Hardcore: The Japanese box art is full of cute anime-style characters, while the American box art is a grim fantasy with a guy fighting a monster.
- Autosave: This game notably featured autosave back in 1992.
- A scene of the hero resting with Gum Drop in a shack and literally battling his romantic desires was cut overseas.
- Several enemies were changed to have less religious themes in keeping with NOA's censorship policies at the time, and a naked mermaid enemy was given armor to wear.
- Card-Carrying Villain: Bio-Haz is a textbook Evil Overlord trying to conquer Greene Kingdom, and he's generating as much pollution as possible because it makes him and his army stronger. It's not until the end of the game that you learn he has another motive besides his great greed; he wants to save the human world from pollution by using Greene Kingdom as its garbage dump.
- Dummied Out: The Naughty Desires enemy was censored in the English version to Foxey. The scene featuring the enemy ended up cut completely overseas, leaving it unused.
- Edible Theme Naming: All the friendly NPCs and regions have food-related names. For example, the five princesses are named Candy, Cup Cake, Truffle, Gum Drop, and Citrus.
- Gay Option: You can pick any one of ten other characters, male or female, for your male character to marry after you beat the game.
- Green Aesop: With the evil forces literally powered by pollution, the environmental message is a strong one.
- Hello, [Insert Name Here]: The player decides Sam's name at the start of the game.
- Jailbait Wait: If you choose to marry Cup Cake, who's only eleven, the King insists you wait until she's of age to marry.
- Kitsune: The deleted Naughty Desires/Foxey enemy transforms into a many-tailed fox upon defeat.
- Literal Metaphor: The hero fighting his lust towards Gum Drop in the original Japanese version - he enters the battle screen and beats up a physical representation of his desire.
- Load-Bearing Boss: Upon the defeat of Bio-Haz, his castle collapses and the heroes escape in a balloon. Shortly afterwards recurring boss Sarg is defeated, and his hideout collapses as well.
- Standard Hero Reward: After beating the game, the King will ask you if you want to marry one of his daughters. If you agree, he'll ask you to talk to the one you want to marry. However, you don't actually have to pick one of the princesses - with enough persistence, you can actually marry anyone in the room. In addition to the princesses, this includes the elderly (female) court wizard, two male bureaucrats, the Queen, and even the King himself!
- We Buy Anything: Shops recycle your equipment and any of the useless flavor items. This is also the only way for you to get rid of any TRASH you picked up in a random chest, and thus free up your very limited inventory for something useful.
