Summary
Pumpkins, Donnie thought solemnly, why on earth are we looking for pumpkins in December? He directs a curious glance towards his younger brother, Mikey— the younger teen is humming to himself cheerfully, unaware of the look Donnie was shooting him. Asking the question out loud though, does gain his attention.
Mikey smiles, shrugging his shoulders, "Because it's festive—" he skips over a crack on the pavement,"—and it's Raph and Leo's favorite!"
He shoots his brother an unimpressed glare, which was responded to with an almost anxious look, "C'mon Donnie," Mikey whined, "It'll be fun—Just the two of us!"
He was ready to turn back around, the cold was biting at his face, and he missed the warmth of his lab. But, against everything his mind was telling him to do, he couldn't just abandon Mikey to do this alone. How hard would it be to find some stupid pumpkins anyways? Just the two of us, huh?
or
Mikey and Donnie go pumpkin shopping; things quickly go wrong.
(This is a rewrite of a fic I made years ago. Will update whenever I feel like it.)

Summary
Mutant Subject 003 - Tag Blue: Caution
Found in [Redacted]
[Redacted] has given a statement that [Redacted] once lived with others peacefully, but changed when [redacted] occurred. Extreme trauma has altered the Subject's mental state significantly, and has led to dramatic mutations such as [redacted] and [redacted]
Usagi stared. Unbelievable. Un-fucking-believable. How was he supposed to do his job when the files had been censored to hell. Usagi grumbled, he'll definitely have to go drinking with Gen, that way he could try to get more information from him about whatever the hell this mutant was.
The Baron had some balls to redact a blue-tagged mutant’s file so heavily.

A Foot Too Big by NinjaNekosLibrary for Teks_Emporium
Fandoms: Teenage Mutant Ninja Turtles (TV 2012)
25 Nov 2025
Tags
Summary
IMDb: When the Turtles discover Bigfoot in the woods, Donnie befriends it and insists they protect it from a hunter.
Improved: When Donnie and Mikey discover Bigfoot in the woods, Donnie befriends her and insists they protect her from a prowling hunter. As they soon learn, Big Foot wants much more from Donnie than his friendship.
(This IS a non-con story and there IS sexual themes, but sexual intercourse never takes place. This is an exploration of the scenario that the episode sets up (and then ignores) on the topic of grooming. The SA depicted is not glorified or appraised in any form. This fic is better categorized as horror. If you're looking for romance, you're in the wrong fanfic.)

I Won a Part of You by CursedCatChild

Summary
The Techno drone wasn’t meant to be ever separated from its pilot. Yet Donnie forcibly got ripped out of it. But that never meant that the Techno Drone also got ripped out of Donnie. Or that the softshell’s parts all come back with him. What will a turtle do if he finds out that he’s partially Krang and that part is actually the majority of him?
Or the Techno Drone didn’t just Krangified, but straight up made Donnie 70% Krang. Of course with a species change comes some freaky new instinct, issues and body horror worthy transformations. Drowning in intense self hatred and fear of losing his brothers ( especially his twin) of course he tries to face all these challenges all alone.
Basically another Krang-Donnie AU, but trust me this is going to be a rollercoaster of very gory, very sweet and have a lot of made up Krang lore you never knew you needed.

Title is from the song Heart by Rainbow Kitten Surprise
He doesn’t know why it was now of all times that his brain decided to let him in on this little revelation that his brain has apparently known forever. He couldn’t tell you why this of all things was the reason he snapped, but in hindsight he definitely should have seen it coming.
Donatello Hamato would never be able to forgive Splinter for the over a decade of neglect.
Not even if his life depended on it.Or; Donnie snaps at Splinter for all the years of severe neglect after he tries to wake up Leo.
