Harry, Hermione, and Ron were under the invisibility cloak walking down to Hagrid's (like always). While they were walking down they decided to do something new for once. They knock on the door. Hagrid opens it.
Hagrid: "Who's there?? Harry, Hermione, Ron is that you under that ruddy cloak?" No one answered. Hagrid went inside. Harry knocked again.
Hagrid: "Whoever that is stop!! *mutters under breathe* man I need to take my medicine I'm hearing things again.
When Harry when up to knock again he turned into a......... that's right A LLAMA! Harry was so surprised he thought about a lollipop. Then everyone at Hogwarts turned into llamas and died. The end

Don't ask I was really bored.
