Taking another look at what was announced under the Behaviors section of the new Firmware 2.1.0/2.1.1 I think your little EMO might not like it, (see below).
This is what was shared by WayneZ in the official post: (see here as well) - I’m guessing you’ve already seen/read it. BUT too scared to let your little monster know about it 
Behaviors:
- New animation when EMO walking into obstacles, which takes time to see.
- Response to sudden yelling and vibrations such as knocking on the table. This mostly works when EMO’s staying, sleeping or walking around.
3. EMO will give different explanations when voice commands cannot be executed.
a) I can’t do it on my charger
b) I can’t do it now
c) Ok, but I prefer to do it standing on a desktop
d) Sorry, but please first put me on a desktop - The “Be quiet” command will make EMO stay where he is for an hour.
So, I’m thinking that maybe the skateboard response might not be brought back, and yes charger doesn’t sound the same, but as mentioned, let’s see if @Wayne_Zhang can provide further clarification on whether it could be brought back.
At least if you decide to update your EMO to the latest Firmware he’ll at least be able to tell you the time in 12-hour format That should keep him a little under control… for a while
