Onni always had a great time with his grandad in winter because his grandad would teach him how to ski and they sometimes went for trips in the nearby woods.
When Onni turned ten, his grandad told him he was old enough to go with him into the Finnish wilderness. Therefore, one day, they put on their skis and set off into the forest, travelling for several kilometres while the sky turned dark above them. Eventually, they arrived at a silent and beautiful wooden cabin. Grandad managed to push the door open. Inside, it was icy-cold and smelled damp and musty.
"Now we need a fire!" said grandad. He pointed at the pot-belly stove in the corner.
They collected armfuls of wood and chopped them up. Before long, a fire lighted up the cabin with a golden light! The old man pulled out a pan and began frying some sausages.
Onni stared out of the window. "What animals live out here?" he asked. "Oh, the forest is full of life!" his grandad answered. "I have seen snow hares, stags, bears and snowy owls. There was only one creature we never managed to see."
"What was that?" asked Onni. He was curious!
"Firefox! They say that during the day: his fur is inky-black. But at night, it shines with the most amazing colours! The light of his fur is supposed to brighten up the night sky at midwinter creating the wonderful glow that we call the Northern Lights, which always guide the people lost in forests."
Grandad sighed. "I always wanted to see this beast! It is said that whoever spots the Firefox would be blessed." Hearing this Onni looked out of the window again in the hope of being the lucky one.
Grandad turned the sausages over as they sizzled (发出咝咝声) in the pan. "Why don't you get some more firewood, Onni?" he suggested. Onni ventured out (冒险外出) again. As the boy was gathering more wood, he heard a sound and saw a glow in the trees.
