Jelloid (The One Doctor)
From Tardis Wiki, the free Doctor Who reference
A lonely Jelloid was a Spraxis Jelloid who guarded a giant diamond on the planet Generios 15 (under a 50 million year, non-negotiable contract) and swallowed the Sixth Doctor when he tried to steal it, but eventually regurgitated him. He came from a long line of distinguished single-celled organisms. He was waiting two million years for an entertainment system. He was a very lonely jelloid and wrote a song about how lonely he was.
