I made a new discovery about the Yeti.
Here is what happened:
Yeti: What an audience! I've gotten better reaction from a frozen tundra!
Me: LOL LOL Lol Lol lol lol Is that better Yeti?

Then the Yeti started acting like he was laughing really hard. So I said lol again and he laughed again!

Do you know if the other NPC's have any secret reactions to any secret words?

uh.. ok? i kind of understand if u say something they might respond. ill try that

sounds cool
i'll try it out

I tried it, it didn't work for me :( Ah well I'll try it with Captain Blackheart later

CapElDano was there it worked for him. It may just be random I don't know.

The Yeti can laugh? :| O.o

~Cake

it works every so often
but one thing:
does the yeti laugh by throwing snow? lol

Hmm, not sure, bob. LOL Maybe I will investigate! Yeah sometimes it works and I don't know maybe its random. But the only time I have ever seen it work is when I was in that room and said lol. Maybe its just a coincidence.
