Sparky is a goat with white fleece, brown skin, dark brown antlers, and a spiky quiff. He has blue handkerchiefs on his arms, and he wears brown sandals.
Sparky is depicted as a jock character of sorts. He is the strongest of his group and enjoys sports and showing off his strength to others. He's quick tempered, and quick to act, often charging headlong into dangerous situations. He has a romantic interest in Tibbie and is always on the lookout for opportunities to impress her. He likes to pick on Paddi.
- His name is similar to the Chinese word "沸沸扬扬" (Fèifèiyángyáng) which means "noisy", or exactly to describe "too many discussions that are as tumultuous as boiling water with bubbles coming out", or "everyone is talking about something".
