Fox has released its fall schedule for the Fox Box Saturday morning block programmed by 4Kids Entertainment.  In addition to returning series TMNT, Ultimate Muscle:  The Kinnikuman Legacy, Kirby, and The Cramp Twins, Fox is premiering a number of new series of interest to pop culture retailers.  Sonic X, based on the Sonic the Hedgehog videogame property, will premiere in the 9:30 slot.  Archie produces a comic based on the Sonic property.  Cubix moves over from the WB.  Funky Cops, described as '70s nostalgia and outrageous comedy,' is the story of two cops/disco stars in 1970s San Francisco.  And as we've previously reported, anime series Shaman King will also premiere (see 'Shaman King on Fox Box in Fall').  The new programming starts Saturday, September 6.
