Smitty,
No, my penguin walking foot didn't come with mine, but funny story. I bought it on a trip about 2 or 3 years ago and it got lost in the storage area of our VW camper van. DH brought it in last year and I went "oh"...I had forgotten I had found it. I have now seen them priced at $650 (prior high was $500)...I told him about it so he would know and he said sell it, I said what are you crazy, I'll never be able to replace it :-) . I don't know what I paid for it but I bet it was around $20 or so, altho I did know how expensive they were when I bought.
I took pictures and will upload them as soon as the board seems to have settled down.
