HI EVERYONE! So in the american version of Hotel Mario when Bowser laughs at the beginning he has a slight echo. Source: https://www.youtube.com/watch?v=-Dv_DXqdC9k

While in the french version he doesn't have an echo at all for some reason.

Also, Bowser is called Bosswor in the french version.

That's all for now.
