Hooloovoo

A super-intelligent shade of the colour blue. Contributed to the engineering of the Heart of Gold on Damogran, where it was temporarily refracted into a free-standing prism for the unveiling ceremony.

"...and a Hooloovoo (a Hooloovoo is a super-intelligent shade of the colour blue). All except the Hooloovoo were resplendent in their multi-coloured ceremonial lab coats; the Hooloovoo had been temporarily refracted into a free-standing prism for the occasion."

— The Hitchhiker's Guide to the Galaxy, Chapter 4

A Hooloovoo is a non-corporeal, super-intelligent shade of the colour blue recognized across the Galaxy for its peerless grasp of hyper-dimensional physics, optical mechanics, and probability theory.

Physiology & Chromatic Existence

Unlike carbon-based bipeds, reptiloid atomineers, green sylph-like maximegalaticians, or octopodic physucturalists, a Hooloovoo possesses no solid anatomical limbs or physical torso:

  • Pure Wavelength Sentience: A Hooloovoo exists as a coherent, self-aware electromagnetic waveform occupying the brilliant azure band of the visible spectrum.
  • Ceremonial Protocol: Because a shade of blue cannot wear a multi-coloured ceremonial lab coat, formal diplomatic and academic protocol dictates that an attending Hooloovoo be temporarily refracted into a free-standing prism so that it may stand alongside its humanoid and non-humanoid colleagues at receptions.

Contribution to the Heart of Gold Project

On the secret oceanic research world of Damogran, a Hooloovoo served on the elite scientific team that went beyond the furthest limits of physical laws, restructured the fundamental fabric of matter, and strained, twisted, and broke the laws of possibility and impossibility to build the starship Heart of Gold.

During the ship's grand unveiling on the cliffs of the island of France, the Hooloovoo stood refracted inside its free-standing prism among the reception committee—sharing in the general thrill of meeting Zaphod Beeblebrox and his orange presidential sash moments before being frozen in place by Zaphod's Paralyso-Matic bomb.
