"From Atlanta-based underground animation studio Mike the Pod ("Moonlight Sonata", Bear With Searing Gas Pain") comes a bare-fisted tale of white-knuckle action! Unkempt security guard John's right arm was transformed into a costumed super-limb after being stuck in a vending machine (stocked with irradiated soda).
