Sunnyville is a beautiful place to live. The residents are a friendly bunch and everything looks pristine – until one day Rhino drops a sweet wrapper on the floor and everything starts to spiral out of control.

“What? says Rhino “It’s only one…” – but of course it’s never as simple as that. Soon everyone in town thinks it’s ok to drop litter and the streets start to pile up with rubbish.

The mess makes Giraffe very unhappy so he picks a flower from the local park to brighten up his home. “What? says Giraffe “It’s only one… – but the town’s flower beds are quickly emptied as everyone picks ‘just one’ flower of their own.

Things go from bad to worse when Pigeon decides to play music in the park to cheer himself up. Yes – you’ve guessed it. Just one song!
