If I may add one thing: Do not hump someone in a mascot or fursuit
One would think this is a no brainer but last year it was an issue for my group more than once!!!
My friend was Gir last year and she had several people gesture at her with 3 different people who ran up and physically humped the suit, with one wrapping themselves around her leg!
Another guy humped my sister's Arcanine quadsuit, security saw this and they pulled him to the side, I am not sure what they did with him because we promptly left the area...BUT... from what I understand such contact is considered sexual harassment and is punishable by not just the con staff but also by the police system.
I understand you may think it is funny, I understand you are just playing (at least I hope to gawd you are) and I understand that when you cannot see the human inside there is a disconnect and you may not be thinking of the human inside. But for my friend she found it very gross to have people thrusting their hips against her like that, she is afraid to even wear Gir again...and I personally think it is disgusting behavior even if they do not touch you.
If it were a Sailor Moon cosplay you would think twice about running up and thrusting your hips at her right? Please remember there is a human inside that mascot cosplay, it is not a giant walking toy, please respect the costume as a human... please. Thanks.
