The mother kangaroo in Winnie-the-Pooh is Kanga.
Kanga is a female kangaroo and the devoted mother of Roo, her young son. She appears in A. A. Milne’s original Pooh books, Winnie-the-Pooh (1926) and The House at Pooh Corner (1928), and became a recurring character in Disney adaptations.
Kanga and Roo arrive in the Hundred Acre Wood during the seventh chapter of Winnie-the-Pooh. The other animals initially regard Kanga as one of the “Fiercer Animals,” but they soon discover that she is kind, practical, and protective rather than frightening. Her name also forms a pair with Roo’s: together, “Kanga-Roo” resembles the word kangaroo.
Roo is the answer’s most important common mix-up. He is Kanga’s son, not her name, while Lumpy is a young Heffalump introduced in Disney stories. Kanga was based on a stuffed kangaroo toy owned by Christopher Robin Milne. In the books, she is the only female character among the principal animal characters and later offers Tigger a home-like maternal welcome.
