Baloo (from 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 sloth 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, the panther, save Mowgli from Shere Khan, the tiger, and endeavour to teach Mowgli the Law of the Jungle in many of The Jungle Book stories.
