"I tried answering, but the answers are pointless."
— Corobo

The Worrywart Kingdom (悩める国, Nayameru kuni) is the fourth kingdom explored by Corobo, located southeast of the Skull Plains and west of Alpoko. The Worrywart Kingdom is led by the worrisome King Omelet, and populated by the Eggan people who, like their king, spend their time philosophising over many questions and endlessly worrying.


Of the seven rival kingdoms, the Worrywart Kingdom is the smallest, only occupying 2% of the entire World.The Worrywart Kingdom is themed after anxiety and eggs, the latter of which is likely a metaphor for the idea of shutting out, a common symptom of Generalised Anxiety Disorder. In line with this, the Eggans and many signs throughout the Kingdom challenge Corobo and by extension the player with many questions about the nature of life and purpose. The Kingdom also explores the idea of thinking about thinking, and worrying about worrying, two other symptoms of Anxiety Disorders.

Nature Maze

The Nature Maze

Omelet is aware of who Corobo is and what his goal is before he even reaches Worrywart, likely due to his nature of thinking and knowing so much. He invites Corobo into his Kingdom, as long as the young king invests some time to think about why he is there in the first place. When Corobo first arrives at Worrywart, he is met with a reverse-cutout of himself in front of the Worrying Labyrinth, meaning he has to leave his Royal Guard behind and explore the maze alone. Aside from a few stray Cockadoodledo UMA, the area has almost nothing to prevent Corobo's trespassing into the Kingdom, leaving him to become lost in the maze and read "Whispers" about the downfall of a person's life, up until their death. This person is never identified.

Past the maze lies the center of the land: a small grove surrounding a large egg, at the centre of a spiral pattern. As Corobo inspects this egg, the Eggans living in the Kingdom begin to emerge, still lost in a cycle of thinking. After some time, some of the Eggans accuse Corobo of being a murderer and an invader as a result of his quest to take over the World. Corobo eventually becomes angry and punches the egg, causing it to crack and shatter, revealing another egg underneath, like a matryoshka doll. The Eggans notice this and begin to surround Corobo, but his Royal Guard arrive in time to protect the King. The battle against Omelet begins, who is not present, but his voice asks questions and guides Corobo through a quiz. Each correct answer causes another layer of the egg to break apart.

The Giant Egg after the battle

The final question asks who the true menace to the Worrywart Kingdom is: in response, Corobo and his people attack the egg and crack open the final layer, to reveal Omelet inside, on a toilet surrounded by books, shut off from the rest of the world. After interrogating the young king on how he feels about his goal and how great it truly makes him, Omelet gives up the Kingdom and requests that he remains within the egg, on the condition that Corobo comes to terms with the implications of his actions. Omelet, and by extension Corobo, ultimately conclude that no matter how much thinking, some answers are unobtainable, or pointless, bringing the anxiety analogy full circle.

After King Omelet is defeated, this area becomes the Eggan Civilization Ruins, and Alpoko becomes inhabited by a single Eggan. Many eggs then appear throughout the Kingdom, which can be broken by the Alpokian Eggan.


The music in the area is a slow cover of Dvorak's "Slavonic Dance No. 2". The theme is played on a low whistle with a synth bass, and adds new supporting piano melodies, such as for the intro to the piece.


During Omelet's Quiz battle, several other UMA appear as answers:

  • Due to its size, the Worrywart Kingdom distinctively lacks features that other kingdoms have.
  • The Bird's Nests in the Skull Plains appear to have Cockledoodledo and Concodore UMA that have migrated from the Worrywart Kingdom, since the two are within such close proximity of each other.
