"og" That's cool. I'm pretty sure it will stay, from the looks of it. South Bay Geckos has one with a happy face on it, and I have one with a perfect heart on it's nose. Let's hope they stay.
How cute! I guess my odds of hatching out a gecko with SBG on it would be the same as hatching some new mutation... smiley face gecko patterns will have to do! (I hatched two like that from the same pairing this year!)
