EMO does not sing the song until the end and show the cake 
not like in the genuine animation there is a bug I Think
Also when you ask him give me a cake he scans your face ?!?!
Hello so no help on that ???
The animation you know from the video is not the same and currently there is no command where EMO only shows you a cake.
These animations will come with future updates, all current commands can be found here: Voice Command - LivingAi
