Yeah I been watching these animations too, but I dont have my gramaphone working yet so I kept wonder what he's hearing that im not.
But the one animation I thought was funny was the Bosun sneaking a taste, and Olaf waving the knife at him and the Bosun just kept at it.
But they are just routines not tied to anything properly cause I also saw Olaf doing the same thing later on, and the Bosun wasnt even there but sitting in his bunk. Lots of things like this though, and no one is on the other end of the show. The crewmember is waving and apparently talking but no actual speech is heard, and there's no one in front of him. Or in the bunk below as some are doing this from their bunk.
There also animations that occur if you click on them when in close enough proximity. Usually just truning towrds you and nodding or something.
