Su is the more heavier ghost, which he and Uh scare and take photos of any guest who decides to waltz into the house. and will do pratically do anything for the attention of Lah, even if that means beating the hell out of a werehog XD.

For the voice, cant necesarrily think of anyone who would sound similar to what im thinking. I kinda want more of mixture of a deep sounding voice, not patrick star deep, kinda in the middle. or the similar to the grunts and noises he makes during the short. of course you can do what you think best fits Su.
