Tidal Wave, Splash for short, is the little guy on the left. He's the youngest of the three and by far the most energetic. If you can get him to stop talking then you're either very skilled, or just very lucky.
Chained Links, Link for short, is the girl in the middle. Technically the middle child, she's serious most of the time and hardly talks. Her orange markings will shift position occasionally and link/re-link with the other rings
Shadow's Edge, Shadow or Shade for short, is the guy on the right. Technically the oldest child, he and Link are twins. This one makes Link seem like a chatterbox as he rarely speaks, and when he does it's often in a soft voice that could easily be lost against any other sounds. While the eye you can see in this pose is white, his other eye is green. The two sides often swap colors

I'm not actually sure what these three are, a cross between a canine and something else maybe? Or something like that
