Cool!  What percentage of Sea Cow pieces are used in this?

There's details in the link, but I think the creator used all of his Sea Cow pieces, but augmented it with some additional parts.  I don't recall if he knew exactly how many, but I'm guessing the part that makes up the bank.

I'm not sure this would be the right thread to post my MOC since it doesn't use a lot of parts from the official set. On the other side, it's made from the 70816 parts completely...[emoji3]
