Hania's room smelled of crayons and cocoa. The sun was laying golden rectangles on the carpet and the curtains rippled like sea waves. A backpack with navy blue peas was rocking on a chair. Hania put down her notebook, sighed contentedly and ran to the kitchen as her mother called for dinner. As the door quietly closed, the room became very quiet. Calm - but only for a moment. - 'Can someone move me away from the edge of the chair? - muttered Pea, a.k.a. the pea-backpack. - I don't like hanging by one strap! - Now, now! - jumped down from the tabletop Crayon Green, green from tip to tip. She had a soft voice and was always the first to help. From the depths of the pencil case leaned out Pencil Grafi, pointy-nosed and striped. Accompanying him was Puff's Eraser, plump and pink, and the Straight Ruler, always straight and very proud of its centimetres. The pencil sharpener twisted the screw vigorously and rang with a quiet clink. - Ready for an evening stroll around the desk? - yawned Pucia. - Pst! - shook the peas on Pea's fabric. - Hear that? Something rustled in the room. Shh... There seemed to be a thin whisper trembling in the air. Very thin, like the thread of a spider web. - Pssst... hey... here... - it came from somewhere close by, almost from under Pea's nose. All eyes turned to the small pocket at the front of the backpack. The zipper shone like the moon, and a soft light flashed in the crevice. Someone, or something, whispered again, a little more boldly. - 'I think it's this pocket,' said the Straight Line seriously. - You have to go up and check. But carefully. - I can push the lock,' suggested Eraser Puff. - I'm soft, I won't scratch it. - 'And I'll light the way,' volunteered Crayon Green and jumped onto the edge of the desk, where rays of sunlight danced. - 'Look, it's bright in here! - 'Strategy: bridge and climb,' planned Pencil Grafi snootily. - Simple, arrange like a bridge. Ruler Straight solemnly lay down between the desk and the chair. Twist moved first, spinning the screw like a wheel. Zielka trotted right behind him, and Pucia took short steps, leaving tiny trails of rubber dust. Grafi walked behind to keep an eye on the whole team. When they reached Pea, the backpack bravely straightened its straps and stopped swinging. - I feel ticklish,' he said in a whisper. - Right in the middle of the pocket... the kind of bzz, as if someone was holding a little ray. - A ray? - repeated Twisty with his eyes wide open. - Sounds like an adventure. - Shh - the Straight Ruler admonished him. - We are working. Pucia leaned on the zipper and pushed gently. The zipper rustled quietly, as if afraid to wake the curtain of fabric. Zielka leaned over and put her ear to her pocket. She heard... bim? no, more of a tick... tick... and that whisper again, a little shy, a little asking. - Can you hear it? - Grafi asked. - What is she saying? - 'I don't understand everything,' whispered Crayon Green. - Just this: hey... here... me... and something about the light. - I'll be the one to pick up the shore - decided Pucia. - But I need some help. Simple, lock the slider so I don't go too far. Ruler Straight slid under the locking wheel and held it evenly as best she could. Twister positioned himself next to it, ready to spin if anything needed to be loosened. Pencil Grafi climbed up the pea pattern and stood at attention. - Three, two... - whispered Pucia. At the same moment, a bright, warm light flashed from her pocket. It didn't hurt the eyes, rather it tickled the cheeks, like when the sun peeks out from behind the clouds. Inside, something quietly rattled, like a drop of water in a glass. - One... - Pucia finished and pushed a little harder. The lock vibrated. Pea held her breath. All five of them leaned over the little crack. The light danced inside, flicked and... the zipper parted by a finger's width. A quiet sound came from inside the pocket, as if someone had flapped the tiny door. Something moved very close to the edge, so close that Zielka saw the shadow of a round shape. - Oh dear... - whispered Grafi. - Ready? - asked the Straight Ruler almost silently, gathering the courage for one last push, when suddenly something inside touched the lock from the inside and....
