>>7775662>>7775678>>7775685The birds (and pretty much all other Rahi, for that matter) of the Matoran Universe were made in labs of the Brotherhood of Makuta- they don't know what fucking is, and even if they did, they still wouldn't be able to copulate. But what I find interesting is that this would mean that each Rahi was made with a purpose in mind beyond "let's fuck"
granted that purpose was probably usually just "maintain this flora/fauna so it doesn't get out of hand"
