Rumors swirl about that the G.I. Joe Mighty Muggs (and Mighty Muggs in general) may be going the way of the Do Do, but mightymuggsforum.com denies those rumors, and in fact, has posted images of some potential upcoming G.I. Joe Mighty Muggs. Among these items is Zartan, Shipwreck (w/ Polly), Serpentor and a COBRA Trooper. Info can be seen at their forums here, and the images are mirrored below.
Thanks to HissCommander from The Terror Drome for the info!
