One summer morning, Ola woke up earlier than usual. The sun was shining brightly and colourful rays were dancing in her room. - It's a perfect day for an adventure! - thought Ola.

The trees here were different from everywhere - they had blue leaves and purple flowers, and the birds sang cheerful melodies.
