She was animated by Gary Goldman.
Big Mama is the first to discover the newly orphaned Tod, and is quick to comfort the young fox. Together with Dinky and Boomer, she arranges for Tod to be adopted by Widow Tweed. When Tod grows older, she takes notice of the irony of Tod's best friend being Copper, who is his natural enemy. When Copper is taken away on a hunting trip, Big Mama takes Tod aside and explains the dangers of his friendship with Copper. Big Mama shows Tod the numerous animal skins that Copper's owner Amos Slade has hunted down, and tells Tod that Copper will be a trained hunting dog when he returns, and thus a danger to Tod. Tod initially rejects Big Mama's advice, claiming that Copper would never hunt him.
When the adult Tod is released into the wild, Big Mama flies to the forest. While searching for Tod, she finds Vixey, a female fox who grew up in the woods. Big Mama arranges for the two to meet, as Tod has no idea how to survive in the wild. Big Mama didn't reappear or mentioned in The Fox and the Hound 2.
Role in the series
In the Spongebob series, Big Mama reprises her role in the film. However, she later gains a larger role where it is revealed that she and her older cousin, Friend Owl, are in fact agents of the High Council sent to protect their part of the North American Woods worlds, dispensing wisdom and protecting the more vulnerable critters in the forest. Big Mama soon joins the Shell Louge Squad after Amos Slade is defeated, becoming a wise woman to Kairi on her Mark of Mastery Exam and Spyro on his quest to complete his kung-fu training and discover both themselves, the 14 Princesses of Heart, the 14 Guardians of Light and the 13 Seekers of Darkness. In Pocahontas, Big Mama plays the role as an assistant to Grandmother Willow.
