BAM Exclusive elements are usually recolors of existing elements, or occasionally a new mold that are designed specifically for the Build-A-Minifigure bar at LEGO Stores, Legoland Discovery Centers, Legoland Parks etc. These may be a head, torso, lower body, hairpiece or Minifigure accessory released for a Specific Holiday or Season, Halloween, Christmas and Spring are recurring themes. BAM is usually released by Quarters annually, generally referred to as Q1, Q2, Q3 & Q4.  A lot of the non-exclusive BAM parts are CMF parts from previous years, there have been many cases of torsos appearing in BAM that are identical to their CMF counterparts but lack the back printing.  This section will require a lot of research, so like other sections I will start with my personal collection and build from there with help from the community.
