Wow, I would have come to the same conclusion. I guess the best thing to do is to start calling Elton, Ella and hope the two of them figure things out a lay a nice big clutch of eggs for you. Are they Green Tree frogs? If so, I could easily catch several and ship them to you for the cost of shipping if you want a better chance at having a pair.

Edit - oops, I just remembered that you are in Canada. How complicated is it to ship live frogs across the border?
