Yugopotamia is almost the complete opposite of Earth. Everything Earthlings love, they hate, and vice versa. Chocolate is poisonous to them, hugs burn them and they are afraid of things that are happy, healthy and fun. Although the Yugopotamians can be considered war-like people, due to their stupidity and choice of weapons (I.E. bombs made of candy), they are of little danger to the people of Earth. By that same token however, other more dangerous aliens have been known to threaten the Yugopotamians, such as The Gigglepies, Bodacians, and The Darkness. One running gag is that most people from Earth who have been told about Yugopotamia call it 'Europe'. Yugopotamia is exactly 1,000,000,001,000,000 miles away from Earth, shown when Timmy wanted to send Vicky 1 million miles away and Yugopotamia happen to be "one million, one million," as stated by Cosmo in Totally Spaced Out
The planet is covered in a very alien terrain, with strange looking plants and oddly shaped rocks jutting out of the planet's surface.
Yugopotamia and its inhabitants were first introduced in the episode "Spaced Out".
Yugopotamia celebrates F.L.A.R.G. every year, but celebrate on a planet other than theirs due to the last day of F.L.A.R.G. which has them blow up the planet they celebrate F.L.A.R.G. on (hence why it is celebrated somewhere else other than Yugopotamia).
Yugopotamians have a bomb located into their bodies that are activated depending on the celebration of F.L.A.R.G.; If the holliday is not celebrated, the bombs go off.
Yugopotamia was destroyed by the Darkness, but was restored after the events of Wishology since it is okay in the season 7 episode "Planet Poof".
Yugopotamia may have obtained the "Yugo"(serbian "south") from the former country of Yugoslavia, which happens to be in Europe, which may be why people called it Europe.
