I think that they could do things like, when it rains they run home saying things like "Aah!" "It's raining!" "Get inside!" and when they see a zombie they could run from it saying things like "Eek, zombie!" "ZOMBIE!" "Run awaaaaay!" and they could also talk to you like greeting you when they see you and after trading they thank you, and you could talk with them, such as when you hit them they would say "Ouch!" and then angrily ask why you hit them, and you could respond with things like "I'm sorry, it was an accident" "Because you're ugly" "I want you to get out of this building" and you could also do things like kindly ask them to please leave your house or yell at them to get out and then they would attempt to leave the building. They could talk in word bubbles.
