Sputnik

"This pig... some pig. Terrific. Radiant. Humble. Yeah, and she's a pig. She forced me an ultimate decision. A sad decision. Maybe yugam. This pig knows how to use that shotgun, I can assure you. Wonder if I train her with the shotgun?"

--Su Ji-Hoon, Welcome to the Astroblast Space Station

Sputnik is an early teenager and a pig who wears purple and has a normal voice. She is the head smoothie maker at the Astroblast Space Station's smoothie diner, the Frosty Star. She usually likes to be quiet, read books, does puzzles, playing with Jet, and she even loves ballet.

In When the Cold Breeze Blows Away, she serves as a shotgunner of Team Astroblast, which takes part of the Future Alliance and the Sonic Alliance. Like Halley, she is also part of the Preschool Girls as well. She is voiced by Veronica Taylor (but her real name is Kathleen McInerney).
