Duppi child from planet Dup. She was the first to befriend Catherine, daughter of two intergalactic biologists who were on the planet for three years. She played baseball with her new friend but got bored because “Earth games are too easy for us” and always went to play Galgo instead. Catherine was unimpressed with this game until she taught Fasta and her friends a lesson in teamwork. Fasta now looks at sports in a new light.
