Description: A big commotion breaks out in the forest, all because of a single hazelnut. Who could possibly be behind all this trouble? On a peaceful day in the forest, with the wind swaying gently through the trees, something incredible happens: the fierce and terrifying tiger gets his belly stepped on by a deer! The tiger cries out in pain and fury, and now the deer is in big trouble. The furious tiger goes to give the deer a good scolding, but the deer insists it's not fair to blame him — it was all because of the snake. The snake blames the pig, the pig blames the mole, and the mole blames... the hazelnut! But when the raccoon, who's been laughing along as the crow tells this tale, hears the word "hazelnut," he suddenly falls silent and looks terrified. What in the world happened to the raccoon? A delightfully spoken, tail-chasing story told in playful, rhythmic language! Packed with witty illustrations that make reading pure joy! Instead of sharing a delicious hazelnut with a friend, someone tried to keep it all to himself and teased his friend instead — and in the process, accidentally dropped the hazelnut, causing the deer to step right on the tiger. Furious beyond words, the tiger vows to track down whoever dropped that hazelnut and teach them a lesson they won't forget. In Big Trouble!, the story of the angry tiger's search for the hazelnut culprit unfolds in a lively, spoken-style, one-thing-leads-to-another narrative that keeps kids glued to the page from start to finish. Combined with illustrator Jeon Min-geol's signature wit and dynamic artwork, this picture book pulls young readers into a world of pure reading joy. And after the last page, children are left with a meaningful takeaway: seeing how a tiny bit of greed led to such an enormous mess plants a small seed in their hearts — a gentle reminder not to be greedy.
