A/N: Hey guys! I've been having a bit of writers' block, so here's another drabble I did instead! FWI, I do NOT OWN TMNT, NOR DO I OWN 'There's Only One of You'. THAT IS OWNED BY WARNER BROTHERS: ANIMANIACS.

Enjoy!

You

"Donnie?" April called as she walked down the stairs of the old house, turning into the living room as her head turned left and right in search for the purple clad turtle. The only turtles she could find were Raphael, sat on the couch with Casey as they played on one of the video games she owned from her childhood, and Leonardo in the rocking chair leisurely reading a book she'd found in her dad's old study room.

April put her hands on her hip, blowing a strand of hair from her face. "Um, guys? Any of you guys seen Donnie?" she asked. "I need his help to fix the sink in the bathroom upstairs."

All heads turned to look at the young red head; Raph even paused the game out of courtesy. "Uh, I think he said he was gonna be in the barn for a little while last time I saw him," Raph said with a shrug. "He said he had some cleaning up to do or something."

April's brow furrowed. What could Donnie possibly need to clean up? Unless it was the clutter of metal parts from the Kraang ship that he and Casey had used to fix up the 'Turtle Racer'…or the chicken feathers from Michelangelo letting his chickens run wild. She shrugged. "Okay, I'll go see if I can get him out of there for a few minutes. Thanks guys," she said as she made her way to the front door.

"Happy to help," they all called as the sounds of the game resumed in the living room, and April couldn't help but shake her head with a smile.

Boys.

Shutting the door behind her, April tread over to the barn, waving at Mikey from where he sat on the wooden swing. He waved back with a smile. "Hi April!" he called.

She giggled. "Hey Mikey! What are you doing out here?" she asked.

Mikey shrugged. "Just chillin', like a Turtle do. And if you're lookin' for Donnie, he's in the barn cleaning up after the chickens, which was totally not my fault by the way."

April smiled and shook her head again. Boys. "Thanks, Mikey," she said before continuing her course towards the barn, leaving the orange clad turtle to bask in the glow of the afternoon sun. She made a mental note to tell him to go back inside before he ended up getting baked or something*.

Once she reached the barn doors, she lifted her hand to knock when her hand froze mid-knock. Her brows rose as she pressed her ear to the wooden door, listening closely. She could hear Donnie, but he was…humming? Carefully, she pried the door open and peered inside.

What she was presented with was not at all what she expected to find as her jaw fell.

Donnie was swaying from side to side with his eyes closed, a broom in his hand with the wooden end of it brought close to his mouth like a microphone as he began to sing.

"There are fifty-thousand different kinds of animals, and there are fifty thousand more that used to be!

There's a hundred million ants and a half a billion plants, and a lot of fish down underneath the sea!

There's gotta be a couple million spiders, a hundred fifty billion butterflies and bees!

A bunch of different mammals like those elephants and camels, and approximately fifty billion trees!"

With her eyes wide open, April was forced to slap a hand over her mouth to stifle the burst of laughter that threatened to erupt as she watched him dance and sing as though no one was in the room (which had been the case). Of course she wasn't laughing out of spite; his voice was beautiful, and she had never heard him sing like this before, not even in his old lab back in the old lair. It was just the lyrics that had her laughing. They were just so…just so like Donnie.

However, it was the next verse that stunned her the most.

"But there is only one of you, that makes you special!

You stand out among the other things, it's true!

Yes, the universe is large and whoever is in charge made lots of things, but only one of you!"

April blinked in surprise, her hand slowly moving from her mouth as she listened to Donnie with wonder. And it was then that she noticed that there was a picture of her from his T-Phone on his desk. He wasn't…singing about her, was he?

A warm smile appeared on her face as she continued to listen, folding her arms and leaning against the door-frame as she watched him sing with confidence and a big, gap-toothed spread across his face.

"A one, a two, a three and a four! A thousand and a million and a billion or more!

There's a trillion drops of water in the ocean, and a billion, trillion molecules of air!

There are insects here en masse, and a trillion blades of grass, and a thousand strands on every head of hair!

A lot of little grains of dirt make up this planet! A billion atoms on the head of every pin!

A millions birds that all can fly, a trillion stars up in the sky, and all the many different people that have been!"

April's smile grew wider as his voice gained more confidence, and he spun around to point at the picture on his phone.

"But there is only one of you, that makes you special! Yes, there is nothing else exactly like you are!

Cause you're unique and you're terrific! And you're kind of real specific!

There's no one quite the same as the person you became!

In fact, you're kinda weird, but we like you just the same!

Cause you're the only one of you there are!

A babadoo, babadoo, babadoo ba! Yeah!"

Once he finished, he struck a pose before bowing to the seemingly non-existent crowd.

It was then that April started to clap.

His eyes flying wide open, Donnie spun around and released a high-pitched squeak upon finding that April was standing there at the entrance of the barn, beaming brightly as she clapped. "GAH!" Donnie yelped, stumbling over his own feet and landing on his backside as he gawked up at April, his face turning a very dark shade of red.

April giggled as she walked into the barn, her hands clasped behind her back as she looked down at him with a warm smile.

Gulping, Donnie pressed his fingers together as he chuckled nervously. "…um…h-how long were you standing there?" he stammered.

Her smile broadened. "Long enough, Donnie," she said. "That song was pretty good. Did you make that up…for me?"

Scratching the back of his head, Donnie bit his lip. "Um, well, not exactly, I-I mean, um…yes?"

Shaking her head fondly, April sat down in front of him, leaning forwards and wrapping her arms around his neck in a firm, loving hug as she nestled her face into the crook of his neck. "It was a pretty song, Donnie," she whispered against him. He remained stunned for a moment, before his arms encircled her in return as he held her close.

After enough time had passed, the two of them reluctantly drew away. April then held up a finger. "But you forgot something important in your song, Donnie," she said.

Donnie tilted his head in confusion. "What do you mean?" he asked.

She smiled again as she tapped her finger against his chest. "They made lots of things, but only one of you," she sang.

The smile that she received could never be matched.

A/N: Yay, Apriltello fluff! I adore the song, I adore the ship, and I adore Rob Paulsen!

I hope you enjoyed this! See you next chapter!
