Is the alternate ending of riddle school 3 scary

No, despite what people say it's not scary (well it depends on how easily you are scared) because all that happens is as your character steps outside he screen goes backwards and fades to black, then a drawn picture of a monkey fades onto the screen and the words "You have been possessed by the evil monkey doll." appear on screen and the words and monkey slowly fade out leaving only red circles where the monkeys eyes where, then they fade out.
So it generally depends on how easily you're scared.
