The costume seems to be that of the Big Bad Wolf. Not only is it anthromorphic, it also has a baggy, tatted pair of suspended pants.
You take it to the dressing room, strip and try it on. It seems to be well padded, as you look quite muscular. It also feels like your lungs are a lot stronger too, as if you needed to do a lot of huffing and puffing. The constume fits so well you can't even tell when your skin ends and the costume begins.
Walking out of the store and seeing (and smelling) the animals, your mouth waters. It's like a vast exotic smorgesboard of fresh meat!
Unfortunately you can't just jump into the enclosures and gourge yourself or you'll be shot. Instead you decide to wait until after closing hours. For now you go to the cafeteria and satisy your appitite with a few ham rolls.
