So is Surprise in Shrek? It corresponds quite well to the gif you posted earlier. Purge has appeared five times, you posted that gif five times.
I still hope the "tenth house" is an upcharge because if it isn't prices will shoot up and ten (non-upcharge) houses might result in there not being any one house that fits the "all-time great" mold, if that makes sense--though if Purge happens, there's at least one house that will cost them very little. DE2 won't be overly expensive either.
