Pebble is a small, faceted pet rock Toon with a smooth gray body and lighter gray legs. His big, white googly eyes and tiny black nose give him an endearing, cartoonish look, while the hollow clover markings on his cheeks add a unique charm. Despite lacking a neck and visible joints, he moves with a lively, dog-like energy. He cannot speak English but understands it well, communicating through a series of meaningful barks and growls. Pebble is affectionate and playful with most Toons, though he has a short temper and will bark loudly when annoyed. He enjoys fetch and treats, and shows concern for his owner through his interactions.
