The Shrill Pony Federation of Shrillland is a gargantuan, socially progressive nation, ruled by Orange Blossom with an even hand, and remarkable for its unlimited-speed roads, multi-spousal wedding ceremonies, and punitive income tax rates. The compassionate, democratic, cheerful, devout population of 35.333 billion Shrills are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The enormous government juggles the competing demands of Education, Welfare, and Healthcare. It meets to discuss matters of state in the capital city of New Maxia. The average income tax rate is 99.0%.

The frighteningly efficient Shrilllandian economy, worth a remarkable 6,632 trillion Cooklings a year, is extremely specialized and mostly made up of the Book Publishing industry, with major contributions from Tourism. State-owned companies are common. Average income is an impressive 187,708 Cooklings, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Incidents involving lethal string attacks have gone way up, police officers that upset their bosses get assigned to 24 hour stakeouts of bike sheds, the television adaptation of Jennifer Government is the most popular program in the nation, and nature magazines featuring stick insects on their covers are sometimes mistaken for fashion magazines. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Shrillland's national animal is the black cat, which frolics freely in the nation's many lush forests, and its national religion is Celestianism.

Shrillland is ranked 307,256^th in the world and 15^th in Pony Lands for Largest Arms Manufacturing Sector, scoring -28.89 on the Charon Conveyancy Index.
