Mr. Sun enjoys walks about the galaxy and visits from his intergalactic neighbors.  Except Alpha Centauri, who is a little too 'wacky' for Mr. Sun's taste.  Despite these interuptions, Mr. Sun often helps out his fellow Plotcebians by providing lighting direction, as well as joy and warmth.  He tends to be somewhat shy, and keeps his distance from the rest of the crew at times-- approximately one earth unit away, to be precise.  That rarely keeps Mr. Sun from having a good time, though, and he'll surely be in any future Plotcebo productions.
