Two-headed Pigeon

This two-headed pigeon can be seen at the very beginning of Monsters University where it tries to eat a worm crawling on a street when all of a sudden it breathes fire on the worm, burning it in the process and eating it when all of a sudden it turns toward the viewer that it actually has two heads: one with a forked tongue, and the other that breathes fire. The pigeon is then scared off by the Frighton Elementary school bus as it is carrying Ms. Graves' class (including Mike Wazowski) to Monsters Inc. for a field trip.
