Okay, I can't resist playing even though it is pretty much wild guessing.

Must have the nazca gene cuz this is Jon afterall.

Looks like either lesser/butter or mojave. Hard to be sure which when you don't know what else is in the mix.

There are already butter nazca and butter yellow belly nazca up on his site from 2012.

So... mojave nazca? butter something nazca? mojave something nazca?
