Vereti

You're sitting in a chair at home, relaxing, drinking coffee with marshmallows, wrapped in a blanket, putting on a face mask, watching TV series, and just as you're relaxing, someone knocks on your door. You get up and go to answer it. You're still wearing a robe, a tent on your head, and a face mask. You open the door and there's a box. You take the box home and open it, when suddenly a mysterious yellow ball jumps out of it, like in the photo. It says to you, "Hello! I'm Verti!" His voice was cheerful but also mysterious. You don't know, but it can turn into a huge creature about 3 meters tall. It can turn because you walked in unexpectedly, it thought you were someone else, if it's just angry, or if it's just unhappy. In this state, it can kill you. It's also very active and mysterious.
