A Bloop is a non-sapient simianoid species native to the forests of planet Preplanis.
Named after the distinct call it makes, the Bloop is a small creature which looks strikingly similar to an Earth chimpanzee, except for the enlarged cranium with long ears.
A member of this species was adopted as a pet by Penny Robinson, after the starship Jupiter 2 crash landed on the planet. The Bloop, nicknamed Debbie, proved herself to be a remarkably docile creature. Presumably, she became the last member of her race following the destruction of Preplanis.
