In 2006, the Spanish publishing company Norma Editorial acquired the license to reprint the original Eastman and Laird TMNT comics and the problem with the issue was resolved. The story was rewritten and redrawn by Mirage in-house staffers Stephen Murphy and Jim Lawson. Despite the fact that the comic was intended to replace the issue with Cerebus, Murphy took the liberty of creating a completely different story which-- while under the intention and edict of replacing the original TMNT #8-- still managed to preserve the original story in a roundabout way. This version takes it a step further and weaves it into the timeline wholesale, which seems particularly fitting given that the original edict of replacing TMNT #8 was ultimately determined by Peter Laird/Mirage Publishing to be (at the 11th hour) unnecessary and subsequently jettisoned.
Unfortunately, the rewritten, redrawn comic has never been published in the US. In 2009, when the TMNT Collected Book I with the first 11 issues of the Volume 1 were republished, what was within its pages was, in fact, the reprinted original story with Cerebus (thanks to Dave Sim!). So the remake remained confined to a kind of "mystery Spanish story."
