Look out, Jammer! Dr. Mandigo is on your tail, and he's loaded for bear! Shot full of tranquilizer darts, Gordie disappears into the hallucinatory world of his subconscious, where strange creatures and giant Shamans steer him through his own lunacy. But what's more insane -- the mad world of his mind or the mad schemes of Dr. Mandigo? And, of course, the most important question of all: to buy a new TV or stick with the old one? The Jam: Urban Adventure has sprung full-blown from the mushy brain of Bernie Mireault.
