Information was recently released tonight on who will be the third special guest artist for Pushead’s Skeletal Carnival at SDCC on Skeletal. I am sure everyone else is as excited to hear as we are, that the special guest will indeed be Usugrow. We are all wishing to hear news about an SDCC Exclusive Rebel Ink to be released, but we can only hope. In other Skeletal Carnival news, more photos of Mike Sutfin’s custom Rumble Monsters Bop Dragons surfaced on Toybot Studios earlier.Two more phenomenal customs created shown of the many 39 pieces that will be at this awesome event. More photos after the jump. [Source Toybot Studios]
