With Peridot and Lapis as 'Crystal Gems' now, it would be cool to add them in with a new opening. I dunno if they should change the whole song to include them, or at least show them in the opening animation along with the other characters of Beach City.

But the longer we go without an opening with them kinda makes me wonder if their status as Crystal Gems or even recurring characters may be only temporary.

Or maybe at some point they'll both be poofed and then reform with the star on their outfit replacing the diamond, and then they'll be real Crystal Gems.
