Rathalos dialog

[Theodric]

The game is pretty selective about that, not to mention that was an obvious joke dialogue option (not to mention these events aren't quite canon to start with); I liked it, it was funny. Not to mention when you meet Genbu your Kojin partner will exclaim "By the kami! A talking turtle?" to the bemusement of the WoL and Tataru.

My point is, of COURSE it's silly, that's the point

Bartz makes a similar comment when he meets a talking turtle back in FFV, so that particular dialogue line is likely inspired by that. It could be a coincidence, of course, but given how often this game likes to reference previous titles I think it's safe to consider it intentional.
