I don't really have any ideas for racial abilities, because it's been years since I've watched Futurama, let alone the Amazonian episode or the later ones that cameo them. But I did whip up a basic chassis to go from, just add a couple of racial abilities and it should be ready to go!
Amazonian

- 40' speed
