Got the idea from watching Spongebob, the episode Home Sweet Pineapple.

Ron and the Spiders:
Harry sat in bed, looking through the Maurader's map. He felt a strange connection to the map, like it belonged to him somehow. At this time of night most of the castle was sleeping, but some of the professors seemed to be up patrolling or pacing their studies. Harry was considering fighting his insomnia and attempting sleep when movement from Ron's bed caught his attention.
"Spiders! Spiders! They want me to tap dance! I don't want to tap dance!"
"You tell those spiders Ron."
"Yea I'll tell them. I'll…" Ron flopped sleepily onto his pillow.
Harry turned the page of the map when he felt a pillow thrash into his head.
"Spiders! Ahhh! Spiders!"
"Ron! Ron wake up! Ron!"
Ron went back into his bed and continued sleeping. Harry sighed, putting away the map and turning out his light.
"Ahhh! Spiders! Spiders!" Harry felt something hard hitting him. Ron's bedside table!
"Ron! Ouch! It's me! Ron! Wake up!"
Suddenly Ron was sleeping peacefully on his bed again.
Harry's breathing was ragged as he stared at his best friend. Finally he decided it was safe to sleep. He settled into bed and closed his eyes.
An ungodly snore erupted from Neville's bed and Harry's eyes shot open.
"Can't you people sleep quietly!" he screamed.
"God Harry, keep it down. We're sleeping." Seamus said as he rolled over.
Harry's eye started twitching. It was going to be a long night.
