The Hedgehog in the Iron Mask
In this episode the Sonic Underground rescue a prisoner from one of Robotnik's old prisoners - a hedgehog wearing a mask (so you can't see his face properly). The prisoner claims he is the hedgehogs uncle, the twin brother of Queen Aleena! But it is all just a sinister plan by Robotnik to split the Sonic Underground up.
