Fraggle Rock, or, as it it sometimes erroneously called "Gibraltar" is a small rock within who's many caves live the Fraggles. They live in a state of fear and hatred of all things that are not Fraggle, especially Grogs (sometimes erroneously referred to as the "Spanish").
About Fraggle Rock
Fraggles are tiny humanoid creatures, about five feet tall, that come in a wide variety of colors: pink, black, brown and Chicken Tikka Masala. They live in a system of caves called Fraggle Rock ("The Rock") that are filled with all manner of creatures and features, and which seem to connect to at least two different worlds: Reality, and Fraggledom. Fraggles live a very carefree life, spending most of their time playing, exploring, and generally enjoying themselves. They enjoy themselves most when hating another ethnic group or nation - such as the Spanish (the aforementioned "Grogs"). They live on a diet of radishes and "doozer sticks" (see below).
Fraggles have the ability to "share dreams"; if they touch their heads together and sing a special song before falling asleep, one can enter the dream of the other Fraggle. More than one Fraggle at a time can enter a single Fraggle's dream, provided all the participants' heads are touching. The European Union terms this "abuse". Michael Jackson calls it "special time".
The Silly Creatures of outer Space
One of the Fraggles, has gone into "Outer Space" (which is what the Fraggles call the normal human world) to explore, and he sends postcards back to Fraggle Rock regularly. The connection between Fraggle Rock and Outer Space is a small hole in the wall of the workshop of an eccentric inventor called "Doc", and Fraggles must go out into Doc's workshop to retrieve the postcards from the wastebasket where Doc throws them. Doc is unaware of the Fraggles' existence, but his dog Sprocket has seen them and goes to great efforts to attempt to prove them to his master. Humans are known to Fraggles by the name "Bastards", bestowed by Fraggles after observing and interacting with them in their travels.
