Uhh so I might have written something inspired by Heckl's comics and drawings :] go check his comics/artwork out!! Hope you like it (and happy birthday!!) (Also if there is any mistake... well, lets say its because it is 1 am)

When it came to playing video games the twins would always end up getting too invested in it, which either would turn up to them fixating on the game for hours or fighting over who could beat it in “the right way”. Even when the games were two player ones, they’d still do the same thing.

Not so surprisingly, this didn’t change even when Donnie became twice his size. Instead now the boys were sitting in Leo’s room, Leo laying his back on Donnie and playing the new the Legend of Zelda game on their switch. Donnie was watching the screen with joy, his tail wagging, and at times chirping to Leo.

“See? I can do the puzzles quite well.” Leo said without looking away from the screen. “I had told you.”

Donnie chirped as a response, as if making fun of Leo.

Leo turned to him, “Just because I got stuck it doesn’t mean I am not good with them. Now let’s go back to the depths, since somebody thinks I can’t handle it.”

The double mutated turtle smirked, making turtle sounds, before noticing something on the screen and pointing.

“Wha- oh shi--!” He yelped as he moved with Donnie’s arms holding him, making various sounds in the meantime. As Leo turned back his attention to the game, bleeping as he continued playing it with Donnie commenting at times once again. Just like before Donnie’s situation, as if nothing had changed. Everybody in the lair would agree this was nice.

Neither of them was sure how long had passed when Mikey entered with a smile on his face. “Are you two still playing Tears of the Kingdom?” He asked as he approached them.

“Yep.” Leo replied.

“It’s been five hours.” Mikey said.

“Uh-huh.”

“Which means nobody would say anything if I interrupted you for very important reasons.” He grinned.

“Wrong.” Leo responded.

“Don’t think Raphie or dad would agree.” Mikey said, knowing very well that he was right and the two would hear about how they shouldn’t sit down and play video games, forgetting to take care of themselves such as eating. Not to mention how Raph would take this to his advantage and get the switch for himself, not letting Leo play for the rest of the day.

The slider sighed and starred at his younger brother, knowing very well that Mikey had won. He saved his game and put the switch aside. Meanwhile, Donnie huffed from behind. “Soooo tell us about whatever that is very important?” Leo asked as he got up.

“I was thinking about how long the lair has been the same, and about how nice it would be to redecorate it.” Mikey explained.

“You’re the artist Mike, not us.” Leo pointed out.

“Weeeellll, I wasn’t only thinking about art. Remember the Christmas lights?”

Leo squinted at Mikey. “You want to decorate the lair with Christmas lights.”

“Yes!”

“In August.”

“Yeah!”

“…”

“You’ll ignore Halloween?!” Leo gasped, a bit dramatically.

“We can have Halloween later on!” Mikey retorted. “I just want to have some bright lights around, and maybe a few other new stuffs. A colorful lair wouldn’t hurt anyone, instead it would bring joy! Also, it is for art and creativity!”

“So, you mean you want to,” Leo snickered, and his brothers knew what was coming. “Lighten up the mood.”

Mikey groaned, while Donnie growled, both hating the pun. Leo giggled at his own joke, proud of it.

“Ignoring Leo’s terrible pun for my sanity, all I am saying is it would be nice if you could help.” The youngest said.

“Eh, sure.” Leo shrugged, not that he could say no. Donnie got on his feet too, careful to not accidentally knock anything down. He was still getting used to his new size.

With Mikey’s lead they walked out, heading to where Mikey already had the boxes filled with Christmas lights. “We can start from here, and then move to the living room. Leo, can you get the lower parts done?”

“Call it done already.” The slider winked as he walked towards a box.

Mikey joined him, grabbing lights from a different box, “Donnie can you help me? I need to reach the higher parts.”

Donnie chirped as he leaned for Mikey to climb on his shoulders, just like how he did with Raph. He carefully climbed and then patted Donnie’s shoulder to confirm he was ready. Donnie churred happily, he stood up again.

So, they began redecorating the lair with the lights, leaving some walls empty so Mikey could draw on them. In the meantime, they chatted, talking about various things and unimportant stuff. Filling the silence with happy chatter. Mikey would talk about his next art projects, then mention something that inspirited him, Leo would ask about it, and the conversation would go on.

It was just like every single time they spent time together, yet it was everything Donnie could ask for. The chatter of his brothers, Mikey’s unexpected ideas, Leo’s dumdum jokes… It was comforting for him.

So, comforting that---

CHURRR

Leo and Mikey stopped talking, looking at Donnie with surprise and glee. Donnie confusedly looked Leo and then at Mikey. As silence was the only answer, Donnie realized what he just had done. His brothers’ exclamation confirmed his fear:

“OH MY GOSH!!!” Mikey grinned as he jumped down to see Donnie better. “DID YOU DO THAT?!”

“DID YOU JUST CHURR?!” Leo wheezed.

Donnie chirped a lot, trying his best in his situation. It didn’t help that Leo kept laughing, and Mikey kept saying he sounded like a happy cat. Maybe if Donnie was his not double mutated self, he would’ve acted cooler and kept calm. But he was not and all he could do chirping. Which frustrated him even more, resulting him running out of the room.

Leo and Mikey were quick to follow him.

Donnie had lay under a pile of clothes, most of them being his hoodies and some of Raph’s sweaters that Raph had helped him wear (and later Donnie hadn’t let Raph get them back) in his room. His tail was visible, wagging angrily.

The two brothers approached carefully, not to startle him. Mikey looked at Leo, unsure what to do or say. He was feeling a bit bad for Donnie, but he still couldn’t help thinking that he behaved like a cat. Leo wasn’t feeling much different. He knew that he shouldn’t have laughed that much, while Donnie was still upset with his double this whole situation.

Leo was first to speak, “Uh hey Dee, mind if we join you?”

A growl.

“Aww come on, we got something to show you.” He said cheerfully, Mikey looked at him confusedly. The slider winked at him, meaning he had a plan.

Donnie didn’t leave the pile, but got his head out of it, enough to be able to see them. Leo grinned, and then chirped. Donnie’s eyes widened, surprised, and confused.

“I thought you had stopped doing it and were unable to anymore.” Mikey squinted at Leo.

“Well, maybe Donnie’s chirping has helped me figure it out, couldn’t it be?” He spoke.

Before Mikey could say anything and tell his disbelief, Donnie chirped.

Leo turned his attention back to him, “I have absolutely no idea what I am saying though, but- chirp!”

“Are you sure about not knowing what you’re saying?” Mikey questioned.

“Chiirp.” Leo smirked.

This seemed to lift Donnie’s mood a bit though. His tail was wagging in the happy way, and he began chirping again. Mikey joined too, since he never had hidden the fact that he still could chirp. Soon the room was filled with chirping of every sort, and the snickering of Mikey and Leo among them at times when one of them made a funny sounding one.

As the boys' conversation changed with the passing time, Leo turned to Mikey. "About the Christmas lights... you're definitely up to something." He said. "Could it be a prank against Raph?"

"Please, I would never." Mikey responded, obviously guilty. He didn't need to say it to confirm Leo's guess when he happily stimmed the way he'd do when he was excited for something.

"Get ready for a surprised Raph yelp, Dee." Leo looked at the clock on his phone. Then looked at Donnie. "He'd wake up any moment now."

Donnie chirped in response, letting Leo pet his back. Something that kept Donnie relaxed, they'd discovered.

Then they heard the surprised yelp, as Leo had guessed:

"ITS CHRISTMAS?!"

Leo and Donnie turned to Mikey, who was giggling. "Brumation prank," He grinned. "Never gets old."
