Bigmouth

Ducky, a Bigmouth

“	"You lummox! You dropped her!" "Of course I dropped her, the little bigmouth bit me!"	”
— Pterano and Sierra, The Land Before Time VII: The Stone of Cold Fire

Bigmouth is a term, roughly synonymous with "Swimmer", that is sparingly used in The Land Before Time franchise. It is only used in The Land Before Time and The Land Before Time VII: The Stone of Cold Fire. It refers to Ducky's kind; though she uses it to describe herself in the first movie, with the narrator also referring to her as such, its use in the seventh movie, by the character Sierra, is in a pejorative manner.
