This secret achievement is completed while doing the Amazon level. Be careful! If you miss this achievement during your first run-through of the Amazon level on a playthrough, you will not be able to access the Amazon level again until you either complete the game or start a new playthrough!
When you get to the second part of the level (the temple area), on the first "floor" of the temple on the very right of the screen, there will be a dubious looking statue. Pogo smash the statue (this will also give you ~300k-400k extra money, so I would recommend going for this achievement if you're grinding away the the art or money achievements) and the achievement will pop.
I am posting this video guide to help give you a better idea of where to go and what to look for. I take no credit for it, I'm just posting it to help you visualize what I'm explaining in this guide.
