This is kind of an oddball one.
Looking through an old sketchbook, I came across this page. It's not dated, but from the contents, it had to be written before I plotted issue number seven of the original "Tales of the TMNT" book, because I clearly reused some elements of the plot for THIS proposed crossover.
I am not sure what inspired me to come up with this idea, but I have to say, looking at it now, that it would probably have been a lot of fun to work with Mike "Gizmo" Dooney and Jim "Bade Biker" Lawson on this.
And zombie dinosaurs could have been neat. -- PL
