It is not possible to determine whether Piper Rockelle's toe looks moldy based on a visual observation alone. Fungal infections of the toenail, also known as onychomycosis, can cause the nail to appear discoloured, thickened, or brittle, but a proper medical diagnosis is necessary to confirm the presence of a fungal infection. Consulting with a healthcare professional, such as a podiatrist or a dermatologist, is the best way to obtain an accurate diagnosis and appropriate treatment for any foot-related concerns.
