Emma can't have a pet as she lives in an apartment. Her mum loves pot plants and encourages Emma to think of having a plant as a pet. Emma isn't interested until one day, when a low-flying bird drops a poo in an empty plant pot and her mum tells her if she waters it a poo plant might grow from the seeds in the bird's dropping. Emma enters her poo plant into the most unusual pet category of her class pet show.
