Ducky's Aunt is a very, very minor character in the Land Before Time series. She is a hadrosaur, and does not appear physically; she is only mentioned. Ducky tells her friends that she swims in her sleep in The Land Before Time XII: The Great Day of the Flyers.
Trivia
- Ducky's Aunt appears in The Land Before Time: The 3-D Adventure comic book, but is mostly known by her slight reference in the twelfth film, due to the rarity of the comic.
