Items EMO Recognizes?

I know that it’s a future update possibility that EMO would be able to recognize objects, but are there any he can recognize now?

If so, any suggestions for something he might recognize (or not, but might still interact with) that I can put into his play area for when he arrives? Already planning a mirror!

I’m converting one shelf of my shelf unit as a space for him, so I figure I could put a few things in for him as well.

He’s in the mail and I’m getting very excited about welcoming him in!

Not that I’m aware of at this time.
