In the quiet corners of Sullivan’s room, a plush toy mouse sat on the study desk, forgotten by everyone except time. This toy, named Oliver, was left behind by Sullivan's cousin during a visit and had been a cherished, chubby companion made of soft, plush material. His round, endearing appearance once invited hugs and playful moments. However, fate took an unexpected turn when Sullivan’s father brought home a mysterious alien liquid. The substance seeped into the toy, causing a bizarre and transformative reaction. Oliver, the once chubby and cute plush mouse, began to change. His limbs elongated, becoming slender and agile, covered in menacing horns and spikes. His once soft and round tail morphed into a devilish, spiked appendage.
