Incomplete CGG Series?

[WedgeAntilles]

I love my 21s with the rhino on them, heck I got both small and large. I'm curious though, all the listings said it's number 3 of five in the big 5 game series. They've also done the leopard and cape buffalo, but I've not seen an elephant or lion. Anyone know if those will be 31s, or did they just not complete the series, or have I just missed something entirely?

I am guessing the series will be completed with the 31. They still have to make the Elephant and Lion. Since the Big Five is now The Big Six, they could add the Hippo to the mix.
