does this count?:
My football (Soccer) team, has a mascot called 'wolfie', a few years back, we were against Bristol City, they have 3 mascots, the three pigs from the popular nursery rhyme. One of the guys inside one of the pigs must have sadi something to out mascot, because Wolfie started properly beating the crap out of one of the guys inside one of the pig costume, full on punching
it was funny, but the guy got fired afterwards [V] which is a shame, cus it was good.
It's not a theme park mascot, but it was mascot abuse
