Literally all I know about this[]
I don't know much about it but I know that it's part crocodile, part fish and part toad. It has an extra mouth where every joint is. In aztec mythology this is the giant earth creature. When it's asleep the people enjoyed the fruits of the earth but once it awoke and stretched the earth shook in deadly movements (earthquakes). It's pretty cool looking to be honest. [a link if you wanna know the actual mythology and stuff behind this creature], I'm just a dipshit so if you want an accurate and detailed description go to the link or do your own research I just wrote this as a shortcut for lazy people like me.
