What if the happiest sound in the park was also the most dangerous?Every afternoon at Oak Grove Park, a street musician plugs in his black amplifier and plays electric guitar under the Great Oak. To the humans strolling by, it's entertainment - a cheerful soundtrack to their picnics and playtime.But to the animals, it's an Invisible Storm.The squirrels who once filled the trees with chatter and acrobatics have disappeared. Kids arrive with bags of peanuts, calling out to friends who never come. Emma, a gentle girl who visits every single day, is heartbroken. She thinks the squirrels don't love her anymore.Scout the raccoon knows better. He's traced the missing families to the far edge of the park - a quiet refuge by the chain-link fence where old pine trees grow. The squirrels are safe from the noise, but they're starving. There are no acorns there. No peanuts. No sunflower seeds. Just silence and hunger.The humans keep bringing food to the center of the park, right next to the roaring amplifier. The squirrels won't go near it. And no one understands why.Scout can't speak Emma's language. He can't tap her on the shoulder and explain. But he can do something no one expects: step out of the shadows, lay a trail of acorns from the Great Oak to the pines, and lead the children to the truth.
