A toy wall ball includes a pair of petals and a connecting portion connecting the petals. Each petal includes a body, a frame extending inward from the body and a magnetic attraction assembly embedded between the body and the frame. Each magnetic attraction assembly includes magnetic members and a fixing member including fixing cases and connecting strips. Each fixing case encloses a corresponding magnetic member and is connected to a connecting strip. When the petals are in a closed state, the petals jointly enclose and define a water-carrying cavity, and the magnetic members of the petals attract each other to have the frames of the petals tightly contact each other to form a water retaining layer that seals the water-carrying cavity. The connection area between the magnetic members and the frame and body is increased, thereby greatly reducing the risk of the magnetic members falling off the petals and improving safety.
