Can confirm this. Tried to reproduce with Octavia Prime and it worked.
Failed any further attempts, happened only once, however i can say it's a rather unique "glass like" sound effect.
I'm in love with every piece of story from the Entrati family. I also want to mention real quick that i am not going to reveal their real names.
I want to say why i love every character in their own way starting with:
1.Otak/Loid (Split Personality)
2. Son
3.Father
4.Daughter
5.Grandmother
6.Mother
I just gave simple reasons why i like/dislike the family so much.
