Grimace

Back before 1975 or so I was actually a four-armed whatever that found it fun to go around ganking everyone's great tasting milk shakes. But after my long run of getting fixes from peoples shakes, the crew of McD's took me into a room and told me I had a problem. After the conflict turned physical while I tried to escape with Ronald's strawberry milk shake, my arms were "accidentally" ripped off and I was sent off to a secret government facility. After a few years of "shake" torture and an incredible amount of weight gain caused as an after effect I came out as the big fat ball of happiness you know today...
