I haven't had a chance to get into the battle yet, but I've been collecting candy at the shops and the towns. I haven't seen an indicator yet as to how many candies I've collected in town, though. However, that could be because I was asleep at the wheel and missed it altogether... wink
I think the chocolate Skittles are included in the ones they give out at the shops. I remember seeing light brown Skittles... which is definitely not from the rainbow. =0
