Think Tank was the mighty ruler of Mars who believed that Martians were superior creatures with handsome looks and high intellect. He had little regard for the inhabitants of the earth and planned to invade the earth. Later, when he contacted his delegates who had landed on earth and were confused to see the books in the Canterville Public Library, they could not make any sense of what the objects were nor comprehend the information therein, looking at the books. Think Tank ordered the crew to consume the vitamins to enable them to decode the information. Much to the amusement of the readers, he misinterpreted the nursery rhymes and thought that the earthlings were powerful creatures and were planning an attack on them. He assumed Humpty-Dumpty in the rhyme as himself and fled to Alpha Centauri to save his life.
