Thanks for noticing those! I always wondered whether people had noticed the lizards or not. We had to incorporate the brand's logo somewhere and I originally planned to add it as a background, but the doll blocked it. So I added it as a pattern as a last minute decision.
It's just a little joke. Sobe has a bunch of flavored drinks, besides flavored water. Well their original, I think, line of drinks that came in glass bottles with metal twist-off caps have funny sayings printed in them. That is my favorite that I ever found. Of course I haven't had a Sobe in a few years so things could have changed.
