Question: The Jungle Book convinces Mowgli to leave the jungle before what evil fictional Bengal tiger arrives?
Context: The Jungle Book is a 1967 American animated musical adventure film produced by Walt Disney Productions.  Inspired by Rudyard Kipling's book of the same name, it is the 19th Disney animated feature film.  Directed by Wolfgang Reitherman, it was the last film to be produced by Walt Disney, who died during its production.  The plot follows Mowgli, a feral child raised in the Indian jungle by wolves, as his friends Bagheera the panther and Baloo the bear try to convince him to leave the jungle before the evil tiger Shere Khan arrives. Mowgli is a fictional character and the protagonist of Rudyard Kipling's "The Jungle Book" stories.  He is a naked feral child from the Pench area in Seoni, India, who originally appeared in Kipling's short story "In the Rukh" (collected in "Many Inventions", 1893) and then went on to become the most prominent and memorable character in his collections "The Jungle Book" and "The Second Jungle Book" (1894–1895), which also featured stories about other characters. The Bengal tiger ("Panthera tigris tigris") is the most numerous of the tiger subspecies.  By 2011, the total population was estimated at fewer than 2,500 individuals with a decreasing trend.  None of the Tiger Conservation Landscapes within the Bengal tiger's range is considered large enough to support an effective population size of 250 adult individuals.  Since 2010, it is listed as Endangered on the IUCN Red List.  An example of charismatic megafauna, the Bengal tiger is the most familiar tiger subspecies, as well as the second largest Shere Khan (Hindi: शेर खान ; Urdu: شیر خان‎ ) is a fictional Bengal tiger and the main antagonist of Rudyard Kipling's "Jungle Book" and its adaptations.  According to The Kipling Society, the word "Shere" (or ""shir"") translates as "tiger" and "Khan" is a title of distinction, used together "to show that he is chief among tigers."  Other sources indicate "Shere" may mean "tiger" or "lion" in Persian, Urdu, and Punjabi, and that "Khan" translates as "king", or "leader", in a number of languages influenced by the Mongols, including Pashto and Urdu.  The name may have originated from the nickname of the Afghan origin King who once ruled in India, Sher Shah Suri. The white tiger or bleached tiger is a pigmentation variant of the Bengal tiger, which is reported in the wild from time to time in the Indian states of Assam, West Bengal and Bihar in the Sunderbans region and especially in the former State of Rewa.  Such a tiger has the black stripes typical of the Bengal tiger, but carries a white or near-white coat. All the Mowgli Stories is a collection of short stories by Rudyard Kipling.  As the title suggests, the book is a chronological compilation of the stories about Mowgli from "The Jungle Book" and "The Second Jungle Book", together with "In the Rukh" (the first Mowgli story written although the last in chronological order).  The book also includes the epigrammatic poems added to the stories for their original book publication.  All of the stories and poems had originally been published between 1893 and 1895. Baloo (Hindi: भालू "Bhālū", "bear") is a main fictional character featured in Rudyard Kipling's "The Jungle Book" from 1894 and "The Second Jungle Book" from 1895.  Baloo, a bear, is the strict teacher of the cubs of the Seeonee wolf pack.  His most challenging pupil is the "man-cub" Mowgli.  Baloo and Bagheera, a panther, save Mowgli from Shere Khan the tiger and endeavor to teach Mowgli the Law of the Jungle in many of "The Jungle Book" stories. Raksha (Hindi: रक्षा / "Rakṣā" or Mother Wolf as initially named) is a fictional character featured in Rudyard Kipling's Mowgli stories, collected in "The Jungle Book" and "The Second Jungle Book".  She is a female Indian wolf, member of the Seeonee pack, who while suckling her own cubs decides also to adopt a human "cub" that her mate Father Wolf has found wandering in the jungle, naming him "Mowgli" (which means "frog" in the Speech of the Jungle) because of his hairlessness. Mowgli: The New Adventures of the Jungle Book is an American live action television series based on the Mowgli stories from the Rudyard Kipling novels, "The Jungle Book" and "The Second Jungle Book".  A contemporary adaptation, the series has Mowgli joined on his adventures by a young American girl named, Nahbiri, who has accompanied her widowed doctor father to Jabalpur, India.  The show was created by Timothy Scott Bogart, Guy Toubes, and James Hereth and produced by Wolfcrest Entertainment and Franklin/Waterman Worldwide, and distributed internationally by Alliance Entertainment.  It premiered on the Fox Kids Network in the United States on February 7, 1998 and ran until March 21, 1998. The Second Jungle Book: Mowgli & Baloo is a 1997 American adventure film starring Jamie Williams as Mowgli, with Roddy McDowall and Billy Campbell in supporting roles.  It is a live action adaptation of Rudyard Kipling's "The Jungle Book" (not based on "The Second Jungle Book", as its title would suggest).  The film was adapted for the screen by Bayard Johnson and Matthew Horton.
