The series centers on a group of teenagers who unwittingly bring about the end of the world through the installation of a beta copy of an upcoming computer game. "Homestuck" features a complex story and a large cast of characters, starring the four children John Egbert, Rose Lalonde, Dave Strider, and Jade Harley. Hussie invented an alien species, called trolls, that have a unique culture. "Homestuck" characters are particularly popular at anime conventions to cosplay.
Document 5: Spalax: The genus Spalax contains the blind, fossorial, or subterranean mole rats, which are one of several types of rodents that are called "mole rats". The hystricognath mole-rats of the family Bathyergidae are completely unrelated, but some other forms are also in the family Spalacidae. Zokors (subfamily Myospalacinae) and root rats and bamboo rats (subfamily Rhizomyinae) are spalacids sometimes referred to as mole rats. Blind mole rats are in the family Spalacidae, but are unique enough to be given a separate subfamily, Spalacinae. Alternate opinions on taxonomy consider the blind mole-rats to be the only members of the family Spalacidae and rank other spalacid subfamilies as full families. Other authors group all members of the superfamily Muroidea into a single family, Muridae. The Spalacinae contains two genera and eight species. Some authorities treat all species as belonging to a single genus, "Spalax".
Document 6: Pearls Before Swine (comics): Pearls Before Swine is an American comic strip written and illustrated by Stephan Pastis. It chronicles the daily lives of five anthropomorphic animals: a Pig, a Rat, a Zebra, a Goat, and a fraternity of crocodiles, as well as a number of supporting characters. Each character represents an aspect of Pastis' own personality and world view. The daily and Sunday comic strip is distributed by Universal Uclick (by United Media's United Feature Syndicate before 2011).

Document 8: Pouched rat: Pouched rats are a group of African rodents in the subfamily Cricetomyinae. They are members of the family Nesomyidae, which contains other African muroids such as climbing mice, Malagasy mice, and the white-tailed rat. All nesomyids are in the superfamily Muroidea, a large and complex clade containing 1/4 of all mammal species. Sometimes the pouched rats are placed in the family Muridae along with all other members of the superfamily Muroidea.
Document 9: Fritz the Cat: Fritz the Cat is a comic strip created by Robert Crumb. Set in a "supercity" of anthropomorphic animals, the strip focuses on Fritz, a feline con artist who frequently goes on wild adventures that sometimes involve sexual escapades. Crumb began drawing this character in homemade comic books when he was a child. Fritz became one of his most famous characters, thanks largely to the motion picture adaptation by Ralph Bakshi.
Document 10: Longtail (rat): On the Isle of Man, longtail is a euphemism used to denote a rat, as a relatively modern superstition has arisen that it is considered bad luck to mention this word. The origins of this superstition date to sea-taboos, where certain words and practices were not mentioned aboard ship, for fear of attracting bad luck (or bad weather).
Document 11: Spalacidae: The Spalacidae, or spalacids, are a family of rodents in the large and complex superfamily Muroidea. They are native to eastern Asia, the Horn of Africa, the Middle East, and southeastern Europe. It includes the blind mole-rats, bamboo rats, mole-rats, and zokors. This family represents the oldest split (excluding perhaps the Platacanthomyinae) in the muroid superfamily, and comprises animals adapted to a subterranean way of life. These rodents were thought to have evolved adaptations to living underground independently until recent genetic studies demonstrated they form a monophyletic group. Members of the Spalacidae are often placed in the family Muridae along with all other members of the Muroidea.
Document 12: Polynesian rat: The Polynesian rat, or Pacific rat ("Rattus exulans"), known to the Māori as kiore, is the third most widespread species of rat in the world behind the brown rat and black rat. The Polynesian rat originated in Southeast Asia, and like its relatives, has become widespread, migrating to most Polynesian islands, including New Zealand, Easter Island, and Hawaii. It shares high adaptability with other rat species extending to many environments, from grasslands to forests. It is also closely associated with humans, who provide easy access to food. It has become a major pest in most areas of its distribution.
