Raph stared back in amazement as he faced the four sisters. They hadn't just rescued some wayward humans like he expected; they were mutants. Three of them appeared to be mutant Turtles, sans shells, and the fourth was some sort of feline/human hybrid with black cat ears on her head.

The sisters soon heard footsteps behind them getting closer, and quickly whipped around to face yet another bi-pedal Turtle, this one wearing a purple bandanna.

"There's like, another one!"

Donny looked back at them, eyes full of fascination. Then he looked down, causing the sisters to shift their focus as well.

It's then when they noticed Donny carrying their fifth sister, also a mutant Turtle, as she laid limp in his arms.

The one who led them gasped. "Rita!" she rushed over, and looked her over. She then looked up at Donny. "Is she going to be okay?"

Donny shook his head briefly as he looked down at her. "Not if she doesn't get some medical attention immediately. I got her to breathe, but it's very labored. Her lungs sound very weak."

One of them began crying. "But we like, can't go to a hospital."

Donny shook his head. "Don't need one." He quickly began walking off.

"Looks like you ladies are comin' with us." Announced Raph as he picked up the remaining two pizzas and began following Donny. "Come on."

With little choice but to follow them, the sisters quickly ran behind the guys.

Donny activated and spoke into his shell communicator. "Leo, it's Donny. Get ready, we've got guests…"

Being their guests were already cold and sopping wet, the guys avoided their favorite water slide entrance, and took the drier, slightly longer route into the lair.

The one who led them looked around. "The sewers…I never even thought for us to hide out down here."

"And with good reason." The feline hybrid said, holding her nose. "Smells awful."

"Just a few more steps, and it won't smell so bad." Donny remarked as they turned down a corridor.

Before long, Raph pulled a lever, and a large cement door opened.

Leo stood, looking towards the entrance opposite the elaborate water slide they often used, as he heard his brothers hurrying in.

"Donny? What's this about gu…." Leo stopped short as he saw Donny and Raph rush in, with the most unique guests in tow.

Mikey stopped mid-chew, mouth agape with a string of pizza cheese hanging out one side as he took in the sight of their guests. "Duuuudeee!"

Hearing the commotion, Master Splinter exited the dojo, only to almost get mowed down by Donny, who was rushing off to his lab holding the unconscious femme mutant.

"Raphael, what is going on?" Master Splinter, just a tad bit alarmed, asked.

Raph gestured towards the confused, sopping wet, shivering mutants standing in the living room. "They fell in that frozen lake in Central Park." He then nodded towards Donny's lab. "Their sister wasn't wakin up, so we brought 'em back here."

Master Splinter felt a pang of pity as he looked at them shivering. "You all must be freezing."

The feline hybrid nodded. "Ohhh you have no idea."

"You cannot stay in those wet clothes, I will bring you some robes right away." Master Splinter turned to Leo. "Leonardo, boil water. They need tea."

"Hai Sensei." Leo bowed slightly, then quickly went off to the kitchen.

"Michaelangelo, get towels."

"On it Sensei!" Mikey exclaimed, quickly stuffing the last of the pizza slice he was eating into his mouth, and running off.

One of the girls grinned as she continued shivering. "They're like, so nice."

Donny took the unconscious one into his lab and gently laid her on a table where he quickly used his vast array of equipment to thoroughly check her vitals. Machines whirred, lights blinked and several warning beeps sounded as he gave her a thorough check up, and worked fervently to stabilize her breathing and revive her. "Just hold on…"

Master Splinter soon emerged from the dojo carrying several traditional Japanese robes draped over his arms.

"Here, you all may change into these." He gestured towards the dojo. "You can change in there. There will be towels and tea awaiting you when you come out."

The girls all graciously thanked him as they took off their backpacks, took a robe, and went into the dojo to change.

The girls soon emerged from the dojo, and Master Splinter handed their wet clothes over to Leo to hang up.

As they sat down, Master Splinter extended his hand towards the tea. "Here, drink. It will help warm you. I'm sure you are freezing."

Mikey soon returned with towels, and handed them each one. "Here you are ladies."

"Thank you, so very much." Said the one who led them as she sat back down after grabbing a cup of tea. She sighed with relief as she delighted in the warmth of the porcelain teacup as the tea it contained warmed her frozen hands.

Donny soon emerged from the other room.

The girls immediately looked up at him with expectant eyes.

"I'm going to need some assistance from one of you." He then turned to Master Splinter. "Sensei, a robe please."

The one who led them set down her tea, and walked over to Donny. "Is everything ok? Is she awake?"

Donny took the robe from Master Splinter. "Thank you Sensei." He turned to the female Turtle eagerly awaiting his response. "She's not awake yet. But she's more stable." He handed her the robe. "I need you to, um, change her into this. The wet clothes are going to hinder her recovery."

She nodded and took the robe. "Of course."

"She's in there." Donny pointed to the door to his lab. "I'll wait out here."

Not too long afterwards, she emerged, holding her sister's wet clothes.

"Thank you." Donny nodded, and went back into the lab.

She nodded in response.

Master Splinter took the wet clothes from her. "Here, I will hang these to dry."

"Thank you." She handed over the clothes, then went to sit back down with her sisters.

The girls sat on the couch sipping the warm herbal tea Master Splinter so graciously provided.

"This is like, sooo freaky." Said one as she leaned towards another with black hair, who was sitting next to her. "They're like us, only bigger. And they have shells. And they're guys."

She nodded slightly in response, though she really wasn't paying much attention to her sister as she looked around at the bi-level sewer home curiously. Then with concerned eyes, she intently looked in the direction Donny had gone with her ailing sister.
