I completely forgot about that Mondo Gecko!
And to be honest, I still don't remember the figure itself, but I do remember that scooter guitar.

For the original toyline, I think Krang and Shredder are the only ones that got true multiple toys. Though the foot soldier did get one vac metallized release. (Not counting movie toys, which I sorta look at as a different line)
Krang got three. The original release, the giant robot that his original toy could fit in, and a more normal sized release of his robot body, near the end of the line. No idea how many Shredder got.
Splinter got a few, I believe. I know April got the most outside of the turtles.
With hindsite, it's amazing that as prominant as they were in the cartoon, Rocksteady and Bebop only got the original release. I don't even think they got repainted and re-released like Shredder did in the toon line, or the vac-metallized footsoldier.
