Bog Scamp

You were raised in the sludgy swamps, and are used to moving through boggy terrain.
  Prerequisites: Kobold, Black-Scaled
  Benefit: You can Swim through a deep bog at up to half your speed as a Move Action, instead of the normal quarter speed. Failing a Swim check while in a deep bog doesn't cause you to go underwater, even if you fail by 5 or more, though such a failure still results in a lack of progress.
