Animation from this film was reused/reworked for a few of Disney's later animated features:
The Jungle Book: The scene of Mowgli getting licked by his wolf brothers is reworked from Wart getting licked by the guard dogs.
The Fox and the Hound: Some animation of a squirrel running across some branches is taken from that of Squirrel!Wart.
The Black Cauldron: The scene of Taran searching for Hen-Wen in the forest is reworked from the scene of Wart trying to find Kay's arrow.
The Princess and the Frog: The scene where Louis wears swamp moss on his head like a wig and makes a crazy face is based on the scene of Madam Mim parting her hair to reveal a pig face underneath.
