I Loved it then and love it now!
2 March 2006 | by (Canada) – See all my reviews

I loved Sonic Underground when i was a kid and Still do to this day. I unfortunately will probably never see this show in a box set of DVD's here in Canada. Oh well I still run around trying to be Sonic or Manic, or Sonia whichever suites my fancy at the time. ^_^ Oh and sometimes I play Knux too! I watch a lot of old cartoons but Sonic Underground has to be one of my fav top tens. Did anyone know the singing voice for Sonic in Sonic Underground now plays Martin Mystery?! I didn't till my brother pointed it out to me. :) But I know Sonic will be around for years to come and I will be there for every new show, comic, game, or toy. And when Sonic Underground does come out on DVD here in Canada, I'm gonna be one of the first there to get it!
