Alas, we'll probably get a Captain K'Rot figure before we get a Captain Carrot figure.
Go here to see more awesome customs pictures: The Fwoosh Forums: The Customs Threads.
Lots of awesome custom-made action figures in that thread, from all over the place. DC, Marvel, Star Wars, you name it. There's even a Darkhawk figure. :)
If you know of anywhere there are more Captain Carrot custom action figures on the Internet, drop me a line and I'll post 'em up on here. And hey, while I'm at it, if you know of any podcasts that have talked about CC&HAZC in an episode or two, let me know about those, too. I'm dying for a CC-centric podcast.
