Big Claw! Spoilers

After I edited the post above 10 minutes ago, I reset my filters and tracked him down again. I tapped him and he took of like a leprechaun (I saw the pill this time) I was able to stay with him until he slowed to a walk and I found that if I continued to tap him he would flash red like an old school dying video game victim. I suppose he has to "recharge" before I can make him drop another pill
