Mama Heffalump is the mother of Lumpy. She is the tritagonist of Pooh's Heffalump Movie. She was worried over her son and has warned him never to leave Heffalump Hollow, as there were scary creatures living outside it, but learned that the other residents of the Hundred Acre Wood are a lot like her. She and Roo’s mother, Kanga, have since formed a friendship.
Mama Heffalump has been occasionally seen in The Book of Pooh, My Friends Tigger & Pooh, but most notably in the film Tigger & Pooh and a Musical Too. In all appearances to date, she has been voiced by Brenda Blethyn.
