Aunt Arctic is the some-what main character in this book.
This is the third book in the Pick Your Path series.
On the front of the book the reporter is Light Blue, but on the back he is Old Blue. It is very likely that this was just the way the lighting was.
In one of the story lines, a crowd of penguins are shouting games for you to challenge the Blue Team captain to and one penguin says, "Extreme Jetpack Surf Carts!", this penguin is probably X-Treme Penguin.
