Fizzgig

Nobody in the clan really knows what exactly this creature is. He LOOKS like a tundra hatchling, but he never seems to grow or change. He followed the coliseum team home one evening after a long day in the mire, bouncing, barking, and occasionally... screaming?
Fizzgig doesn't speak, that anyone knows of. Unless you call the growls and screams that emit from his mouth a language. He mostly acts like a guard dog, and the clan seems to be content with that arrangement. Everyone always knows when a stranger is about to visit the clan thanks to the gravelly howling that this small ball of fur and teeth will unleash.
When he isn't guarding the lair from dangerous strangers, Fizzgig can usually be found in his ever-growing hoard of shiny trinkets (for some reason, he has a very evident obsession with anything that looks like a crystal) and chewable items. And if he isn't found there, he's usually following his next favourite chewtoy around: Nikolai. If Nikolai is in the lair, you can usually find Fizzgig nearby, either barking emphatically at him or chewing on his tail. Occasionally he will climb up onto Nikolai's back and either sleep or simply go along for a ride.
Mostly, this creature's bark is worse than his bite, and he is well loved by everyone in the clan, even if no one really understands him.
