The Belcerebons lived on Kakrafoon Kappa and caused jealousy among their neighbouring civilisations by being enlightened, calm and quiet, behaviour judged to be smug and self-righteous. The Galactic Tribunal as punishment forced telepathy upon the Belcerebons, so that they now must talk continuously in order that their every thought is not broadcast.
The Belcerebons are mentioned in:
- The sixth episode of the TV series.
- From a Latin base, the name would invoke good/beautiful ('bel') and brain ('cerebrum').
