Poo! You Smell! is a storybook app for children aged 2 to 6. When Patsy, a cute dung fly, hatches out from a large squishy cowpat, she meets other creatures that all think she smells horrible. ‘Poo! You Smell!’ is a humorous and heartwarming exploration of how we ‘fit in’ to the world around us. Its based on real science, and we think it is the world’s first story about a dung fly! Despite the prejudice Patsy encounters, the story is resolved happily at the end!
