Shirtle & Crawdad Kid

Here is the last OMFG fan design I'll do for awhile. These fellas are Shirtle and Crawdad Kid, two of my favorite figures. Does anyone get the movie reference?   Also, voting for Series 4 ends this Friday, so don't hesitate to register and vote for your five favorite designs http://www.octobertoys.com/forum/viewtopic.php?f=40&t=11801.
