Poptimus Prime is the world's largest balloon sculpture built by John Reid, a balloon artist from New York. The 50-foot tall Transformers robot, Poptimus Prime made of using 4,302 purple, green, white, black and gray balloons. It was so tall that it actually couldn't fit upright in the convention center. Reid and 10 other volunteers had to struggle a bit to bring it into a kneeling position.
