I believe, it's either fake in one way or another. Especially you can't not notice a lizard when buying. I mean, seriously? You go and pick a bad of such salad and don't see it, and what about person before you and before you who watched and put item on the store. Totally BS.
Even if it's real, the guy is such an asshole he didn't open and left the lizard die of suffocation. I mean, you shouldn't murder animals of such size for no reason at all.
