I for one, think the marathon is a great idea! I speedrun a lot of Mario games and own a Yoshi fursuit, I can play very well in it, and it allows me to do my signature move where I poo out an egg in to my diaper every time I eat an enemy. (You would not BELIEVE how much it cost to get an apparatus for that installed in to the suit xD)

I assume we aren't allowed to make out on camera because kids would be watching (As you said, kids LOVE fursuits, I show mine off to them all the time they get a kick out of it when I let them put their hands up the egg hole ^.^)  But behind the scenes we are allowed to yiff all we want, right? Because if someone starts coming on to me... Let's just say... *Poo egg blush* :3
