"Groosling" refers to a playful term for a young goose, particularly one that is still in its downy feather stage. It is often used in a lighthearted context to describe the adorable, fluffy appearance of goslings. The term combines elements of "goose" and "gosling," emphasizing the youthful and charming characteristics of these birds.
Katniss eats different things in the hunger games. She eats fish, groosling(like a wild turkey, but once plucked the size of a chicken), roots, nuts, berries, rabbit, lamb stew with dried plums, rolls, bread from district 11, mint leaves, and fancy capital food.
