Princess Tomato in the Salad Kingdom

You've got a problem. You're a Cucumber. But you're also a Knight of the Realm, which helps make up for the fact that you go through life long, green, and with seeds. And now to make matters worse, your beloved Princess Tomato has been kidnapped by the wicked Minister Pumpkin, who then boots King Broccoli off the throne and proceeds to abolish all truth, justice, sweetness, and light from the Salad Kingdom. So why are you just laying around waiting to ripen? As Sir Cucumber, you've got to rescue your Princess and save her domain from the power-mad Pumpkin.
