The arm is short, and is covered with a hook like thing ringed by a steel band. The bottom half of its body is ringed by a steel structure—spikes are seen on the top. On the bottom of each spike is a single plate that will split into two near the bottom of the Diet Tank's body. From the bottom of it, two small feet somewhat support the Diet Tank.
