Some items are far higher poly than they should have any right being, while others are perfectly acceptable.

The marshmallow stick has 40 edge rings for what I believe to be ~900 polys, just for the stick, and the pets that were given out on Halloween don't seem to have been un-subdivided!

A few of these items, while being freely available and displayed on mobile platforms, may even end up being VeryPoor if uploaded as avatars there.
