Inside a crate on level 1, you find
A small rubber dog toy in the form of a distraught chicken. So long as it is given to a dog, it performs normally (though with a particularly annoying squeaker). If a human bites it however, the rubber toy begins speaking sanity shattering truths in a maddening language all can understand. A tiny warning label attached to the neck reads "All natural components, do not swallow."
