Just read this in a comment on a less-amazing site "The comics intended for toy pack-ins are produced way, way ahead of schedule, so that they can be ready for the toys. For instance, MTMTE #22, Skids' pack-in issue, was written before MTMTE #16, half a year early."

I'm rereading More Than Meets The Eye from the beginning now, so I might see if it's noticeable, but that's crazy/weird/impressive if Roberts and Barber are not just throwing toys into their stories, but also throwing out their writing schedule in order to do it.
