Gucio sat in his classroom and squeezed his crayon tightly. All around him, the children were painting colourful pictures and Mrs Kasia was going from table to table and looking at the work. Gucio enjoyed drawing very much, but today he felt strange butterflies in his stomach. He was afraid that his drawing would be less pretty than the others. He decided to draw a big, laughing rainbow over a meadow full of flowers. When he had finished, he hid the paper behind his back. Mrs Kasia came up to him and smiled warmly. - What are you drawing there, Gus? - She asked. Gucio turned all red. He didn't know what to say. At that moment something extraordinary happened. The colours in his drawing began to sparkle and shine like a real rainbow after the rain! The flowers began to move and a quiet sound of laughter came from the picture. The children noticed the magical light beaming from Gucci's page. Everyone froze with their faces open and Kasia hopped from foot to foot, unable to believe her eyes. Then little colourful creatures began to emerge from the picture and wave to the children.... Gucio felt great joy and a little fear all at once. Should he tell everyone that it was his drawing? What would happen if the creatures jumped to the floor?
