A Giant Robot Robot

And representing the robots was this robot... made to look sort of like a dragon or monster or living creature of some sort. The "story" was not big on plot - like a twelve year old boy might write. "And then a bigger creature comes out, and then an even bigger robot, and then a super serpent, and then a gigantic robot, and then a fire breathing dinosaur, and they fight and the good guys win". You get the idea.
