Found the 25th Anniversary rereleases of the vintage toys at Target today. $9 a whack, a DVD is included with one of the first five episodes, and they were on generic cardbacks. I remember when these were less than $4 each. As it is, I picked up Raph and Don, since I never had the original versions of those two. Odds are I'll go back and get Mike and Leo because I have an OCD for toys like these.
All that was there was two of each Turtle. I guess the villians and secondary heroes come in a different assortment.
It looks like this is the lineup- the four TMNT, Splinter, April, Casey Jones, Shredder, Bebop, Rocksteady, Foot Soldier, and Slash, who I don't remember coming out until 1990.
