Hello! This is a new Harry Potter Percy Jackson crossover I'm writing with my friend who's uploading this over on watt-pad. Her username is hetalia_fangirls and her pen name, because a couple other friends use the account, is Forever_American. This will be updated randomly, but hopefully you won't have to wait too long between chapters. Especially because we already have, like, ten written. If you are going to say I stole someone's ideas, I swear on the River Styx *Thunder rumbles* I didn't. As of right now I haven't read a single Harry Potter Percy Jackson crossover.

Sheesh that was long, anyway, enjoy!

My eyes widened as I looked at the giant, three headed dog lying in front of me. Hermione hadn't been lying about Fluffy. Sure I had seen some pretty crazy stuff in my life, if you can call men with dog heads normal then go right ahead, but this has got to be the craziest.

"Uh, Harry?" I whimpered, my hand slowly reaching for my wand in my back pocket, "That's a giant dog."

"It's asleep. Snape's already been here," Harry whispered, looking back at us. Ron and I were both clutching onto Hermione's arms, while she was trying not to laugh at us. "The harp," He clarified, pointing to the instrument which was playing itself.

"Are we g-going or what?" I asked, my voice stuttering. My golden blue eyes blinking slowly, "C-cause I-I'm not hanging a-around."

"Yes. C'mon Catriona, lets go," Hermione said, pulling us towards the trap door underneath the dogs enormous paw.

Sighing, I followed reluctantly. By ourselves, we would have never have been able to move it. But there were four of us tonight. We all shoved our hands under the great lump of fur and heaved it up and off the door.

Cautiously, I pulled it open and looked downwards. I swear I saw something moving, but was drawn from my thoughts by Harry saying,

"The music. It stopped."

My head snapped up from the hole in the floor, and I looked over at the harp. The strings had stopped plucking themselves and it sat there in all it's glory, completely and utterly silent.

"But Hagrid said that the only way to put it to sleep was…"

"Music," Ron interrupted me, looking horrified at the harp. Then, a gloop of clear liquid fell onto his shoulders and head.

"Aww, yuck!" He cried, touching it with his hand.

"Eww, eww, don't touch it!" Hermione cried. The shock of the moment quickly surprised us and we all slowly looked up.

The three headed dog stood over us, drool dripping from it's jowls.

I let out an ear piercing scream and leapt down the hole, the others following. With a loud thump, and the odd feeling of slowly sinking, we landed in a pit of vines, "At least the plants broke our fall."

I smiled, trying to pull myself from it's grasp. The vines hugged my legs and refused to let me escape from it's grip.

"NO, PLANT! YOU CAN'T EAT THE HERO!" I screamed, starting to struggle, "I HATE DEVILS SNARE!"

"CAT? HERMIONE? HELP!" I heard Ron screaming. I couldn't see any of the others, and the plants seemed to be eating me faster.

"STOP EATING ME, PLANTS!" I yelped, struggling harder. My arms lashed out and the vines shot forwards, wrapping around my arms and yanking them downwards. I tried to keep myself from crying. I was going to die.

I was going to die because plants were eating me alive, "GOODBYE HERMIONE! IF YOU MAKE IT OUT ALIVE, I HAVE A STASH OF MAGIC BOOKS IN MY ROOM! YOU CAN HAVE THEM!"

"I won't need your books Cat. It's Devils Snare. Just stop struggling," I heard Hermione's voice from below me. She sounded so calm. How could she be calm in a situation like this?!

"THE PLANTS ARE EATING ME, 'MIONE! THEY'RE EATING ME!" I bellowed, completely ignoring her statement. I kicked and screamed, trying to free myself. In sheer desperation, I even bit one of the vines. I spit it right back out again, though, because it tasted like the cleaner dad put on vegetables.

"She's not relaxing, is she?" I heard Harry ask from below me as well.

"She's not. She's always been rebellious and driven purely on adrenaline, hasn't she?" Hermione asked Harry.

"But… Hmmm… Devil's snare, devil's snare… It's deadly fun, but… It hates the sun! That's it! Devil's snare hates sunlight! LUMOS SOLEM!" Hermione cried.

I let out a shriek as I fell and landed heavily on the concrete below. My head connected with the ground and an enormous pain split through my skull. I felt as though I was about to black out and I let my eyes slide shut.
