About Princess Tomato in the Salad Kingdom

Taking the role of Sir Cucumber, a knight, the player is assigned by King Broccoli (now deceased) to defeat the evil Minister Pumpkin who has kidnapped Princess Tomato. Early on, Sir Cucumber gains a sidekick, Percy the baby persimmon, who offers advice and helps throughout the quest.

Princess Tomato in the Salad Kingdom plays similarly to a text adventure, though due to the NES's lack of a keyboard accessory, the possible commands are represented by buttons which line both sides of the screen. The commands are fixed and do not change during gameplay. Primarily, the game consists of still screens with the exception of the "finger wars", mazes and occasional animated character, such as the octoberry and fern birds.

Commands within the game are: MOVE, LOOK, CHECK (used to examine things), TALK, TAKE, USE, GIVE, BUY, HIT, FIGHT (also called "finger wars", challenges enemies to rock-paper-scissors), PRAISE (for flattery), DUMP (for getting rid of inventory items, since you can only carry a limited number), ITEM and PERCY (to get help from your sidekick Percy Persimmon after rescuing him; he always refers to you as "boss"). The only way to "lose" is by not being able to determine which action is required to advance (i.e.: there is no way for the player, Sir Cucumber, to "die" except for in one specific "finger wars" battle).
