SDK is a dragon that is curious, but clueless. Usually when he gets the opportunity to do something, he'll say "This is confusing" or "I don't get this". He's always pushed around by GBX and he also likes to bring his characters into Interviews, which Lemmy hates, although they always get everyone into trouble, that's why Lemmy hates them. Overall, he's as dumb as dirt and overfills his pockets with bazillions of giant, attractive creatures. It is unsure whether he was born on Earth or Plit.
