A/N: Hey readers. This is going to be a short five chapter fanfiction based on the 2014 Ninja Turtles movie. I have never written one of these before, so I really hope it is at your standard. I am influenced by some of the other Ninja Turtles cartoons though; see if you can guess which ones I love the most!

Chapter 1: New Mission

Only three weeks had passed since the people of New York had been saved from Eric Sacks, and only a little more than that since the turtles had met April O'Neil for the first time, but already they were all completely enamoured with her – none more so than Donatello, who secretly thought about her night and day. Unfortunately, Donatello's younger brother Mikey had already called dibs on making the first moves on April (already calling her his girlfriend and coming on far too strongly with the endearment 'sweetcakes'), and was royally botching it up.

To Donatello, that could be great news – as she would never take Mikey seriously as a possible boyfriend, since he had been so forward and crude; on the other hand it was bad news, as perhaps her view of mutant turtles as possible love interests would be forever tainted, and she would never even consider him as a possibility after letting Mikey down – which was likely to happen sooner rather than later, judging by the awkward looks April gave whenever Mikey said something possessive about her.

Donatello could be found locking himself and his laptop in his laboratory every night to do research on the Foot clan's activities - and he found himself more often than not preferring to sleep there so he could avoid hearing his brothers churrs... which had increased in frequency since meeting April. It was no secret that they were all dreaming about her – she was the only human female they had ever meet in the flesh, and all four brothers slept in the same room.

The churrs were a great source of embarrassment for the mutant turtles; there was never any privacy in the lair, especially with them having a shared room, and none found it more embarrassing than Donatello who was now terrified to go to sleep, lest he sleep-churred more than his brothers and any of them were to notice.

Early in their teens they had not had anyone around to tell them what churrs were. Churring made a somewhat unexpected appearance in their life; Raph developed the ability to churr first. Donatello remembered them being angry at Raphael for squeaking what they thought was a soft toy in the middle of the night to wake them up; before Splinter finally established there was no soft toy and it was entirely involuntary on Raphs part as he slept.

That particular night Donatello had locked himself in the laboratory with a map to mark down the Foot clan bases he had researched... when, suddenly, the modified Nokia phone strapped to his shoulder vibrated.

'April,' he gasped in surprise looking at the display. Donatello's hand shook slightly as he pressed the answer button, allowing April's voice to flow from the receiver.

'Donnie?' she asked. 'Is that you?'

'H-hey April, why are you calling so late at night?' Donnie stuttered while gripping the phone so tightly it started to develop hairline cracks.

'Would you be able to come over, please?' April politely requested, 'I think I've found something that might be of interest; it involves the Foot clan. I'll tell you when you get here'.

'I'll be there in ten', Donnie replied hanging up. Donatello poured the rest of his coffee down his throat and quickly attached his computer equipment and bo staff to his shell before quietly exiting his laboratory. His brothers were all sound asleep and Master Splinter's door was closed, so he left a scribbled note on the fridge before leaving the lair and heading for the van. With any luck he'd get back before they even woke up, so there would be no repercussions and no lecture from Leo and Splinter, and no Hashi time. Even if he was caught, Donnie was confident he could talk his way out of the Hashi as he had left a note and was helping April. He just wasn't taking his brothers…

Climbing up to the balcony outside April's apartment some time later with his usual ninja stealth and grace, Donnie straightened and realized that April was already at the window lifting it open.

'We need to hurry', she said by way of greeting.

'What's going on?' Donnie asked as he helped her climb out the window.

'Uh… where are the others?' April inquired, looking around and staring up the fire escape into the gloom.

'Still in bed', Donnie replied, his heart dropping. Perhaps he should have woken the others up after all... 'What's this about?'

'Well it won't matter if it's just you and I, I suppose,' stated April. 'Eric Sacks is out of hospital now. He rang me today to boast of how we didn't completely scuttle his plans'.

'WHAT!' exclaimed Donnie in shock. The last he'd heard of Sacks was that he'd been left comatose – possibly never to awaken after the gun battle April and Vern had with him in the laboratory of Sacks Industries Ltd.

'He still has some of the mutagen, Donnie – not enough to immediately endanger New York like he was planning, but enough to mutate another creature so that he could grow it and harvest the mutagen from its blood later'. April wrung her hands and fingered her handbag. 'We'll have to break into the Sacks Estate tonight to grab it before it's too late. Once he's mutated the creature he could hide it anywhere until it is fully grown'.

'Alright', replied Donnie, 'Should be a simple enough in-and-out job since you already know your way around his estate. We'll just sneak in and out and they'll never know we were there'.

'Yeah, that's what I'm thinking – I told you before that I spent lots of time there as a child – he sort of pretended to be a father figure after dad died and I had lots of visits up there. I never suspected what he was really involved in, though'.

April followed Donnie down to the street where the van was parked; they hopped in and set off towards the Sacks Estate. It would take them a couple of hours to reach their destination, but Donnie couldn't have hoped for better company.
