What was surprising to Neil, at least, was the fact he recognized quite a few staple costumes. From clowns to witches and various animals, both real and mythical (though real enough in Equestria). Some were minimalist, like the green mare he saw wearing only a white flower collar with large petals surrounding her head. On the other hand, some were quite complex, like the two-headed chimera costume worn by two foals waiting to bob for apples.
