Old-Timey Bubs works at the Parsnip Depot, the Old-Timey Bubs' Concession Stand. He has a stripe on his midsection, prominent buckteeth that move while he speaks, and his own shop, just like his modern-day counterpart. He speaks with a very wheezy voice (just as the current Bubs has a very gravelly, raspy voice). He can play the banjo. In addition to having only one leg, Old-Timey Bubs may be visually impaired, based on his dark glasses and tin cup.
He is presumably the son of Mark Grave and was apparently buried alive. Therefore, since the tombstone in Cholera Acres Cemetary bears the legend "Unmarked Grave | son of Mark Grave", it is possible that "Unmarked Grave" is his name. He has never been referred to by any name.
