It's school...it's snowing outside.You heard other students talk about a new student named "Nightmare" And after a while,the teacher came in gesturing someone to come in

Teacher: "Come on in, Nightmare."

A tall young guy with black tendrils (tentacles) came into the classroom

Hello..My name is Nightmare.And i'm new here...

Teacher: "Alright,now pick any free seat!"

Other students in the class kept whispering at how weird Nightmare looks like...
