Friendly Floyd is a unique character that appears in the 11 chapter manga we will be doing. He is a very cheerful and happy character, even though he essentially scams Mario. He appears quite often throughout the series.

I picture his voice sounding a bit like a more friendly and happy version of a car salesman. He is a salesman and originally meets them by trying to sell his wares. He shouldn't sound as scummy as a stereotyped car salesman though.
