It was a typical humid afternoon at Rivervine High, but something felt off. Polly, with her bright green skin speckled with hints of gold, hopped through the cracked halls of her beloved frog school, the echoes of her jumps reverberating in the stagnant air. The walls, once adorned with colorful murals of swamps and sunny skies, were now peeling like shedding bark, draped in shadows that whispered of neglect. Rumors had been swirling around the school about eerie noises at night, strange sightings by the lily pond, and a former principal's mysterious disappearance years ago. As Polly crossed the courtyard, she noticed a large hole in the ground where the old science lab had stood, and a chill ran through her as she realized that the school's great oak tree, the source of their wisdom, had begun to rot from the inside. Had something sinister taken root in their school? Polly's heart raced as she thought of the possibilities, her curiosity battling with the creeping sense of dread. She could either investigate the dark secrets hidden beneath the broken floors of the disintegrating building or seek out Madame Toad, the oldest and wisest frog, who might hold the key to the school's haunting past.
