Xander, the tiny floating kitten thing suddenly popped up from behind a cuppycake, "HIII" he shouted to sparrow, quickly proceeding to nom on a cupcake.

Xander looked up at sparrow his mouth still clamped on the cupcake "Iunno" he mumbled, chomping as he spoke, "I kinda didn't ask" he grinned rubbing the back of his head and laughing nervously

"Nah,"  Sparrow said, though she felt a slight rush of pride at the compliment.  "I had help."  As if to prove her point, Yusuke Urameshi walked up, taking the box from Claine.
"Sweet!"  He said, looking in at the equipment.  "HEY KUWABARA!"
"WHAAAAAT?!"  Came a voice from the other room.
"SHE'S GOT ANOTHER GUITAR CONTROLLER!"
"SWEET!"
"We'll let you in the band once we finish this setlist!"  Kurama called. 
"Yeah, the guys have been playing Rock Band for the past hour."  Sparrow sighed.  "Hiei's busted my high scores on bass..."  She added the last bit with a slight scowl.

"Heh."  Hiei said, fixed on the screen.  "You'd probably be better than this idiot over here.  He's tone-deaf."
"Cut it out, shrimp!"  Kuwabara grumbled.  "I'm doing the best I ca-WANTEEEEED DEAD OR ALIIIIIIVE!!"
"Maybe you should use a different controller next time, Kuwabara."  Kurama said, trying (and slightly failing) to get through a drum solo.
"Sorry, Boss, forgot you might not know these guys..."  Sparrow said sheepishly.  "The short guy with the spiky hair on bass is Hiei, on drums is Kurama, and Kuwabara's the fail-singer."
"I am NOT fail!"  Kuwabara snapped. 
"And I'm Yusuke, by the way.  Nice to meet ya."  Yusuke pushed past the two of them and sat down on the floor with the large box, taking the contents carefully out and setting them on the floor according to what system they went to.
"They're all from Yu Yu Hakusho."  Sparrow explained.
"The best anime ever."  Yusuke said.  "Because it's MY frickin' LIFE.  And who let Kuwabara have the microphone?!"

"Yeah, I better leave them to their own devices..."  Sparrow muttered.  "They seem to really be getting into that game."  If a fight broke out, she could always use her Deity powers to stop it.
"So, what do you wanna do?"  She asked.  "I've got food, there's a pool over there..."  She felt rather awkward simply standing around.

Sparrow walked outside, watching him.
"You'll get cramps, you just ate a huge-normous cupcake!"  She called.  She sat on the edge of the pool, dangling her legs in the water.

Sparrow squealed, drawing her feet out of the pool.
"Dammit, X!"  She laughed.  "Don't do that!"  She watched as the kitten swam to and fro underwater.
