Abstract: A vibrating toy assembly that can travel along a surface in an unpredictable pattern. The toy assembly is powered by a vibration mechanism. The vibration mechanism has a motor and batteries that are held in a housing. The vibration mechanism is placed into a hollow casing. The hollow casing defines an internal compartment. Once activated, the vibration mechanism vibrates and changes orientation within the casing. As the vibration mechanism changes orientations, the movement patterns of the casing are altered. This causes the overall toy assembly to move in random patterns.
