One morning, Zosia woke up very excited. She was going to meet her beloved dog Fafik in the park behind her house. When they got there, they noticed something really strange: there were colourful clouds hovering over their favourite meadow!

Suddenly she felt a lot of warm bubbles appear in her stomach and she was overwhelmed with great joy. The blue cloud made her a little sad and she wanted to cuddle up to Fafik. - Every cloud is a different emotion! - Zosia discovered, and curiosity sparked in her eyes. Suddenly she noticed a new, shimmering cloud that was changing colours and was bigger than all the others. Zosia had never seen such a strange cloud before! Her heart began to beat faster. - I wonder what will happen when I touch it? - she whispered to Fafik and slowly approached the mysterious cloud....
