Oodle is male. He is a white equilateral triangle with teal outlines and limbs, and his face is rendered in a slightly darker teal. He is a demigod-like being capable of crossing dimensions and is one of the most powerful entities in the show. His personality is very cheerful, optimistic, and kind. He views the contestants not just as performers but as friends and prioritizes their happiness. Having seemingly suffered from long-term loneliness in the past, he tries to be as friendly as possible with others, making jokes and giving prizes to teams that complete challenges first. Oodle values friendship and politeness highly and is very interested in making others happy. However, he can be shy and naive at times, often failing to realize that his actions might make others uncomfortable. While usually patient, he can become aggressive or irritable when pushed past his limits; he once personally eliminated a contestant for criticizing the game. He is multi-talented, serving as a game host, optometrist, mechanic, and baker, but he has academic weaknesses, such as poor cursive writing and failing math in school. He is also a collector who gathers souvenirs from his travels across various dimensions. While he enjoys traveling, he finds many places boring. Oodle sometimes creates chaos with his clumsy and eccentric inventions, but he is very sensitive to cleanliness and hates sticky or dirty things. The house he built is very neat, organized, and decorated as a comfortable space. Inside the house, along with his souvenir collection, there is a torn photo taken with someone from his past. Following certain events, he has also shown signs of caffeine addiction. In terms of abilities, he possesses immense power, including reality warping, object creation, resurrection, dimensional travel, dimension creation, teleportation, shapeshifting, and body modification. He also has several special abilities, such as using rocket boots, various vocational skills, and the ability to transform his body into tools or other forms.
