The thing I discovered, as a mascot at my kids’ day camp, is that all kids want to know is who’s inside the costume.  Even though the whole point of the costume in the first place is that the character on the outside is more interesting to kids.  Inside the costume, I’m just another adult, albeit a sweaty, dehydrated one.  Who’s not wearing much under the costume, because it’s a million degrees in there, though he’s the only one who knows it.
