The adventures of two unlikely friends. When Big and Small accidentally damage Ruby's painting, she challenges them to be quiet and accident-free for just one day. Small thinks this will be easy but it proves harder than expected when he realises it's not easy to stop talking. And Big causes a major accident when he trips up over Small's car and brings the fridge crashing to the floor. In a final effort to have a quiet day, Small puts an apple in his mouth so he can't talk (although he keeps taking it out to tell people that he can't talk!) and Big decides to spend the day under the bed. Meanwhile, Ruby is happily painting outside in the peaceful garden. She finishes her painting and wants to show the others - but she finds Small sitting with the apple in his mouth and Big under the bed, both refusing to leave the house to look at her work until the day is over. Ruby realises that it's better for Big and Small to be their usual selves and puts a plan into action to get them outside. She tickles Small so he drops the apple - she picks up the apple and runs off - Small chases Ruby - Big hears the commotion and runs outside, too. Big trips up again and splats the apple. But it's all OK, it was just an accident. And it's better that they are all in the garden, together and having a good time.
