I do not own Harry Potter or any of these songs. I'd be pretty happy if I did though.

Harry walked into the common room and saw everyone was in yellow rain suits, and submarines were painted on the wall. Harry just stared at everything. All of the sudden a yellow rain cap appeared on his head. Harry freaked out and threw it off. He understood what was going on now. Everyone has been possessed to sing! But who would do such a cruel thing?

Harry started to run up the stairs but stopped when he heard Fred and George singing.

Fred and George: "In the town where I was born Lived a man who sailed to sea and he told us of his life in the land of submarines so we sailed up to the sun Till we found the sea of green and we lived beneath the waves In our yellow submarine"

Fred and george were standing on the couch looking at the common room like they were on a boat. Harry stood where he was. For some reason he couldn't move. He realized that hes getting weak soon he will be singing like everyone else! He can't! He has to save everyone!

Everyone: "We all live in our yellow submarine, Yellow submarine, yellow submarine We all live in our yellow submarine, Yellow submarine, yellow submarine"

Harry covered his ears praying to god that he won't start singing like everyone else.

Fred and George: "And our friends are all on board Many more of them live next door And the band begins to play"

Everyone: "We all live in a yellow submarine Yellow submarine, yellow submarine We all live in a yellow submarine Yellow submarine, yellow submarine "

Fred and George now were dancing under one of the painted submarines.

Fred and George: "As we live a life of ease every one of us has all we need Sky of blue and sea of green in our yellow submarine"

Everyone: "We all live in a yellow submarine Yellow submarine, yellow submarine we all live in a yellow submarine Yellow submarine, yellow submarine we all live in a yellow submarine Yellow submarine, yellow submarine"

After that everyone stopped singing and sat down in their seats and started working on their homework for the next coming day.

Harry who was still covering his ears looked around and ran up the stairs to the dorm and hid under the covers. Hoping no one will sing again and that he was just having a creepy dream. Or is he?

As Harry tried to sleep he remembered how back in the common room he almost started singing. Was Harry the only one who wasn't under a singing trap? Who is making everyone sing?
