Turtle fans are completionists. We want every character ever for some stupid reason, and I admit I was one of those folk for while. Had to seriously re-evaluate once the serious deep cuts started coming out. Anything with a TMNT logo will sell a lot at first, and then taper out if they are the side characters. Every figure sells fast, and then we end up having some peg warmers because they make too much. All of this comes from an avid TMNT collector ha.
