His sidekick, Porpy the Porpoise, is described as a ""zany"" space porpoise. While his appearances on the television series have petered out somewhat, his involvement in the graphic novel is ongoing and is included in almost all of the comics. Porpy was prominently featured in "Porpy's story", a short side-story in which Porpy's background is alluded to by Tek, but not told fully, as Tek becomes distracted by an adventure and forgets about Porpy altogether. In the television show Porpy is voiced by stock porpoise sounds and bubbles.
