This is my least original creation! And for a few reasons: there has already been a pizza-themed box set for the Teenage Mutant Ninja Turtles, and this is a shameless rip-off of the excellent Scooby-Doo Mystery Machine DVD box set. However this being a design I would want to buy, I may as well throw it out there. Plus it was fun to make, so why not.
UPDATE (Aug 27/2012): There is now an official release of a TMNT collection in a turtles van. Below is a pic, more details can be found here.
