In a certain colourful house at the end of the street lived a moppy called Felek. Felek was a very curious dog and stuck his wet nose everywhere. One sunny morning, when Grandma Hania was cleaning under the bed, Felek noticed something strange - a huge hat all covered in stars and feathers. "Hm, what's that?" - he thought and jumped neatly inside. Immediately it became very cheerful! The hat was probably enchanted, because when Felek sneezed, a cloud of pink bubbles flew out of the hat! The bubbles burst, making funny sounds: "Bing! Bong! Boing!" Grandma Hania jumped up all the way: "Gosh, Felek, what are you doing there?" But the surprises didn't end there. Colourful balloons in the shape of carrots popped out of the hat, and then one sock, which started doing a merry dance around the room! Felek barked with joy and Grandma tried to catch the sock, but the sock was faster than the wind. At the same moment Basil the cat came into the room. He saw the flying sock and called out: "Oi, that's my favourite!". He threw himself in pursuit of the sock, causing it to knock over a vase of flowers and wake up Theodore the parrot. The parrot was very smart, but also very curious. She called out: "What's going on here? Why do the balloons have carrot ears? And who is scattering bubbles all over the ceiling?" Suddenly the hat began to shake, and a strange, quiet laughter came from within it: "Hi, hi, hi...". Everyone stopped as if startled and stared wide-eyed at the hat. What was hiding inside? Would anyone else come out of the hat? Anything could happen now!
