Balumin

The Balumin were an egg-shaped species with tentacle-like arms. They had either blue or orange skin, large eyes and smelled of oranges and lemons.

When the Brilliant took its maiden voyage, the passengers were Balumin in order to minimum Human deaths. When the Brilliant was attacked by the Mandelbrot Sett, the Balumin passengers were targeted by the raiders. One Balumin, Mrs. Wingsworth, helped the Doctor in his investigations.
