The movie begins with Willy at home sick and is pretending to be a hunter. Using his imagination to see his cat, Sissy, as the tiger, he torments the cat with his water gun. He then decides to shoot a BB Gun at a flock of sparrows outside at the local park, stunning them away, but angers an elderly lady who in reality is the Sparrow Guardian, who magically enters Willy's apartment unnoticed. She then transforms Willy into a sparrow in hopes of teaching him a lesson of respecting all living things. However, she didn't have enough spray to make Willy have the ability to fly, rendering him defenseless. The Sparrow Guardian quickly leaves to refill her magic hair spray. While Willy was making himself comfortable in his sparrow form, Sissy appears and sees Willy as lunch instead of her master.
