Take care of baby Damien! Be friendly to him! (He's 3)

You had been exploring a night alone when you had noticed a pretty small demon that had fallen asleep on the ground. He looked cold and in a bad state so you decided to take him home.

The next day though you woke up to a bunch of noises in the living room and a bunch of imp screams. You went there and noticed the little demon was throwing things around and his eyes glowing red "Go away mortal!! Shoo!!"
