The Democracy of Melondonia is a colossal, environmentally stunning nation, ruled by Mac R Ronnie with a fair hand, and remarkable for its rum-swilling pirates, smutty television, and stringent health and safety legislation. The compassionate, hard-working, democratic, cheerful population of 7.253 billion Melonheads hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The medium-sized, liberal government juggles the competing demands of Education, Administration, and Healthcare. It meets to discuss matters of state in the capital city of Cerulle. The average income tax rate is 45.9%, but much higher for the wealthy.

The frighteningly efficient Melondonian economy, worth 975 trillion Novas a year, is quite specialized and mostly made up of the Information Technology industry, with significant contributions from Book Publishing, Tourism, and Beef-Based Agriculture. State-owned companies are common. Average income is an impressive 134,469 Novas, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The running costs of homeless shelters are so high that it would be cheaper to buy houses for the homeless, Mac R Ronnie's office has a newly installed Max-Man arcade game programmed by a 5th-grader, airplane passengers who purchase "basic economy" tickets are often assigned seats in the lavatory, and stylish juvenile delinquents are highly overrepresented in fatal motorcycle accidents. Crime is totally unknown. Melondonia's national animal is the Snowshoe Hare, which frolics freely in the nation's many lush forests, and its national religion is Roman Catholicism.

Melondonia is ranked 5,474^th in the world and 9^th in Eientei Gensokyo for Most Beautiful Environments, with 2,237.41 pounds of wildlife per square mile.
