The geese appear in the story The Tortoise and the Geese which Mrs. MacGrady tells to D.W. in the episode “D.W., Queen of the Comeback”. The story is originally from the Panchatantra, an old Indian collection of fables.
Story[]
The geese and the tortoise are friends. When their lake dries up, the geese want to carry the tortoise to a new lake by carrying a stick between them, which the tortoise grabs with its mouth. When a duck insults the tortoise, it talks back and falls.
