Sonia gets down 'n' dirty with Sleet and Dingo (literally), and to freshen up, she and her brothers journey to East Mobius. There, Sonia is reunited with some old friends, Mindy Latour and her father. Mindy gives Sonia a locket, but unbeknownst to Sonic's sister or Mindy, the locket is a tracking device designed by Robotnik. Sonia finds out too late, and soon Mindy's kingdom is swarming with similar wristwatch-style robots, all programmed to capture the hedgehogs! Can the siblings stomp out this bug problem? (thetvdb.com)
