Goldie's Kids are two sapient fish.
The children of Goldie were members of the small underwater community befriended by landlubber Donald Duck when he was marooned at the bottom of the sea by an overdose of Aqua-Pills. Like their mother, they greatly enjoyed watching the sponge-ball games he organized, and were present when the sea critters gave Donald a triumphant return to land once the Pills wore off.
