[We Be Goblins] I can't figure out Vorka's hp

[UsagiTaicho]

So Vorka, the final boss of We Be Goblins, has some weird hp. It says that she has the Toughness feat, and a +2 Con mod, yet somehow at level three she is getting a +12 to her 3d8. By my calculations, she should be getting a +9 (+6 from her Con and +3 from Toughness). Where is that extra +3 coming from? It doesn't look like it's coming from any spell or potion, so what gives?

Favored class?

That would be my bet too.
