I checked around a little... give MexiMart a look. They have all kinds of kid's toys. They're on the third row, C-167.
I have only been there once and did not look at everything. I am from Indiana.
There are a couple of booths that have a large amount of colorful painted metal statues. I did see lizards and stuff as I walked by, but didn't spend time going through the booths. I am sure that they probably have what you are looking for.
I have only been there a couple of times but don't remember anything like that. I have seen turtles and dwarfs but only remember them.
