As far as I know there's no way to create and post new lots in Castaway-I think if there was a way to override it, you'd have to do it yourself. But maybe someone else can think of a way I'd like to know the answer as well.

These are awesome! Wonderful job once again!

Definitely cool-thanks a bunch for these!

Very nice-it's nice to have a different sort of potty for the kiddies. Thanks for sharing!

Definitely excellent. Happy birthday to you! *scatters party favors*

I've got a soft spot for the green, but the white is pretty cool. Any way you could offer it just as another skintone for CAS?
