What do you think of when you hear 'tribe'? The Amazon tribe? The Cherokee Tribe? What are names like that even supposed to mean? They're gibberish in English, and probably something stupid in the native language.

I still think that the Strong tribe is better than Bear tribe or Fish tribe, or even Hill tribe. And in any case, this is a great way to show that Ialu is still only something like 3 or 4 years old, and while he might be too big for the playground he's still not so clever, mostly due to his brain being less than fully developed.
