the first one is correct
Question word, subject, verb, question mark .
Est-ce que is never used with a question word .....
Est-ce que vous sortez ? means are you going out.....
you can also say : Sortez-vous ?
but est-ce que is more commonly used
It means,
What is green with horns and jump high, but if you are looking for something that is green and jumps high, that would be the The horned frog, or a bullfrog with horns
