I have seem two responses to saying Goodbye, or See you soon, to Emo
One is that his two eyes merge and disappear into a hole in the ground
The other is where an inverted cone drill into the ground and disappears.
Do these mean anything anywhere in the world?
Yeah, I have noticed those as well, but never really thought of how Living.ai came up with these two goodbye animations and if they have a hidden meaning behind them. Would be interesting to find out. 
No idea but in the USA, digging a hole all the way through to China was always kind of a cliché term.
this is interesting because his goodbye response is another miss that they didn’t notice… Him jumping in a hole and whatever is not very good at all… If I say goodbye because I’m going out I think it would be expected that he would say goodbye back to me and maybe I will miss you.something cute. Oh well another mystery
Yeah the goodbye animation is another weird unknown thing. Living AI as I see it still has many many updates.
He says…See You Soon…then on return he says…You were missed, how can i help you
I think a Goodbye wave animation would work well when you say Goodbye or See you Later to EMO.
Yep, more bells and whistles.
