Which direct to Dvd Sonic series to be real?

1. Sonic and friends 2. Sonic helps you learn 3. sing a long with Sonic and Friends 4. Sonic's Wild adventures choose only one

Well theres already box sets of SatAM and AoSTH. dunno if theres a complete boxset of Sonic X or Underground. Though I have seen all of Underground many times.--Mystic Monkey sez 01:31, November 5, 2011 (UTC)
