Yes, those are the NPC Villagers, formerly known as
'Testiculate', which appeared on their nameplates.
'Yogscast' {
Xephos, Honeydew} said they look like
Squidward from Spongebob Squarepants or perhaps
Gonzo from the Muppets.
I think they're right both times.
Good to hear someone is working on programming them because right now they're as stupid as animals.
I have one in Singleplayer that was hanging around a certain spot all the time so I built him a little guard shack to stay in.
{then I went exploring and got lost
so he's still there
somewhere, awaiting my return ..}
