Bibinese
In a nutshell...
Bibinese is a species that's usually known by amphibious or underwater species. It involves a lot of "eee" and "eye" sounds.
Naming Convention
Typically a name in Bibinese tends to repeat I's twice and any Y's at the end of names are replaced with I... usually. Sometimes, if there's multiple I's, they'll be seperate.
So Marcy would be Marcii or Kenny would be Kennii.
They also tend to (but not always) relate to the ocean or water or something like that. Like Waiiv's name, for instance. It's pronounced "wave", like an ocean wave. But Aieri's name, instead of having two I's back-to-back, there's two of them, just in different places... also, it doesn't really relate to the ocean at all.
