"Hai, Sensai." The four turtles said, as Master Splinter left the room.

Master Splinter was going to visit his old friend for a week, meanwhile the turtles had to take care of the lair, and the little girl they rescued from the gang of kraangs.

It was a calm night and they turtles were out for patrol when they saw her surrounded by kraangs, and, of course, rescued her.

Currently she was sleeping on the couch.

Or they thought so...

As Master Splinter left the room, they saw a little shadow beside him, hiding behind the door pane.

"Look who's up!" Mikey cheered.

She ran into the other room, getting scared.

"Way to go, airhead!" Raph said and he pouted.

The four heard giggling from the other room and ran inside it.

As the girl saw them, she hid behind the couch, giggling.

Everyone decided to play dumb. Mikey asked, "Where'd she go?"

Leo shrugged, "I don't know."

Raph rolled his eyes and jumped behind the couch.

He popped his head out, "She's not there!"

"Huh?" Mikey got confused and everyone started looking around.

Donnie saw her shadow beneath the table, "She's fast."

"Come back here!" Raph yelled, and she giggled again.

"In your dreams, ninja boy!"

"WHAT DID YOU CALL ME?!"

"Ninja boy!" She repeated and showed him her toungue.

"Wait, don't piss him off!" Mikey warned.

"COME HERE YOU LITTLE..." Raph chased him around the room.

"In your dreams, ninja boy!" She teased. "BOOYAKASHA!" She yelled and jumped over Raph.

Everyone froze.

"What?" Mikey said.

"What, what?" She turned around and looked at him.

"What did you just say?"

"You mean this?" She repeated, "BOOYAKASHA!"

"Yeah, that. How did you learn it?" Donnie asked.

"I hear you yell it all the time." She pointed at Mikey.

"DOUBLE BOOYAKASHA!" They both yelled together.

Raph rolled his eyes.

"I never got your name." Leo said.

"I'm Lauren. But you can call me Lulu!"

"Weird name." Raph murmured.

"Yours is weird-er! Ninja boy!"

"That's not my name, ok?!"

"Awww! Teeny-weeny ninja boy got angry? Awww..." Lulu teased.

"SHUDDUP!" Raph snapped.
