Although Slappy could possibly be older, I think Mr. Wood/Wally is the oldest. I don't know, it just seems more likely to me. Mr. Wood could've possibly been an older model of Slappy. And then about a few weeks or months later, Slappy was made. There is a possibility that I'm wrong, but these are just my thoughts.
