"April, slow down!" Donnie begged over the phone. "I can't understand you."
April caught herself and took a few deep breathes to calm herself. Then she started the story over, and explained to Donnie what she and Casey had just experienced on their way home.
"That is unbelievable," Donnie said after April finished. "I mean, I do believe you. But a boy who can turn into a snake? That does seem a bit unusual, even for us."
"Not the point, Don," April reminded him. "The Monster Hunter has seen me and Casey. If she catches us down in the sewer again, she'll know we're up to something."
"Oh, right," Don replied.
"It also means she's already searching the sewers," April continued. "You guys need to be careful."
"We also need to step up the time table of our plan," Don added. "I'll let the others know. You just get some sleep, okay? I'll call you in the morning to fill you in on anything new."
"Okay, Donnie," April agreed. "Good night."
"Good night, April." Don hung up the phone after April and went to pass on the information to his brothers.

...

The next morning April got out of bed early. She hadn't slept well after spending several hours worrying about what would happen if Abigail Finn found her friends. She got ready for school in record time with almost half an hour before Kaitlyn and Kris came by, and waited for Donnie to call. Fifteen minutes later, her T-phone rang. She snatched it up and answered it before the first ring even ended. "Donnie?" she blurted.
"Whoa!" he replied. "Hey, April. Were you waiting by your phone for me to call?"
"Yeah. I needed to know that you guys were okay," she told him. "I was worrying all night about that hunter finding you."
"Oh," Don said, sounding a little disappointed at the reason given.
"So, what's the plan?" April asked.
"Right!" Don nearly shouted, remembering why he had called. "We're going to wait until it's dark, that's most likely when she'll hunt, and slip out of the lair with our fake monster stuff."
"You guys already made fake monster stuff?" April interrupted.
"Some stuff. We'll be making the rest today," Don answered. "Anyway, while we're setting up fake clues, you and Casey are going to find the hunter and give her false information."
"Won't Casey and I suddenly being co-operative be a little suspicious?"
"We thought of a solution for that. You're going to tell her that you guys are amateur Monster Hunters and didn't want to give away information to the competition. But now you need help and want to make a deal."
"Sounds good. Casey and I will come by after school-"
"No. Not today. We don't want to draw any attention too soon. We'll call you when we're ready."
"Alright. Good luck, Don."
"You too, April."

...

April and Casey went back to her place after school to complete their homework while they waited for the call from the turtle brothers. It had already been such a long school day, and April wasn't sure how she was going to make it through the next few hours. So much had been on her mind, like the Monster Hunter and the super powered teens, that she hadn't been able to focus on school all day. And now she had the same problem with focusing on her homework.
"Hey, red. What'cha get for question five?" Casey asked, but got no response from April. "April?"
"Hm? Oh, sorry Casey," she finally said, snapping back to reality. "What did you want help with?"
"Question five. For our math homework."
April picked up her textbook and read the question, but found herself losing focus again. Her gaze drifted to the window as she watched the sky, hoping it would be dark soon. Casey noticed April's lack of focus and made a suggestion, "Maybe we should continue this later."
Once again, April didn't respond. Instead she continued to stare out the window with the textbook open in her lap. Casey closed his textbook and put it back in his bag, along with his other supplies. He stretched out and laid flat against her floor where they'd been sitting. With hands placed under his head and legs crossed, Casey decided to take a nap before he and April had to do their part in the plan.

...

Casey woke up to a frustrated April shaking him. "Hey, whoa!" he cried out. "What I do?"
"You fell asleep," she told him, not pleased. "Donnie just called. We're on."
Casey nodded and grabbed his gear. They snuck out the window, not wanting April's Aunt to get suspicious about why they were leaving at this time of night. They entered the sewer at the nearest access. Wading through the tunnels slowly, they began to search for Dr. Abigail Finn. Their T-phones were on 2-way communication mode, so the gang could talk freely back and forth, like walky-talkies, while they were engaged in their mission. April kept Donnie up to speed with their progress of finding the hunter and where they were located in the sewer tunnels.
Then, April and Casey heard splashing footsteps. They flattened themselves against a wall as Casey pulled down his mask. They inched towards the corner to peer around and see who it was. As the splashes got closer, the teens realized there were two sets of footprints. They shared a look of confusion as they silently wondered who would be with the Monster Hunter. They continued to the corner, but just as they got there, the footsteps stopped. April quickly peeked around the corner. No one was there. She stepped out a little, trying to get a better look and see if anyone was hiding. Casey got closer behind her, attempting a glance over her shoulder. But just as he did so, a pair of gloved hands phased through the wall behind him and grabbed his shoulder.
"Aaagh!" he jumped into the air and spun around quickly with his hockey stick above his head. April sped around to see what Casey was screaming about and saw an upside down boy drop into her view.
"Hey there," the boy greeted, as April let out a startled shriek. Meanwhile, Casey stared in bewilderment as the masked girl from last night phased out of the wall.
"You again," April said, recognizing the masked teens.
"I was gonna say the same thing," the masked boy retorted, floating down to ground level and spinning to face right side up.
"I thought you said you wouldn't be back down here?" the masked girl asked, slightly irritated.
"Not my exact words," April mumbled.
The girl frowned. "You. Shouldn't. Be here," she nearly growled, stepping closer to April.
"Look," Casey interjected, nudging the girl's shoulder. "We know what we're doing."
Just then the girl flicked her fingers and Casey's feet flew out from under him as he splashed down onto his back. The boy chuckled, and Casey thought it sounded familiar.
"Clearly," the girl commented.
"W-whoa!" Casey stammered. "How'd you do that?"
"Telekinesis."
"What?"
"She can move stuff with her mind," April explained.
"Cool," Casey said, as he got back to his feet.
April turned back to the girl, "By the way, we have a plan." She scowled. "And tripping my friend with your brain power doesn't prove otherwise."
"Is your 'plan' to get caught by the Monster Hunter?" the masked boy asked. "Because if so, you're on the right path. Literally. The hunter's right down there." He pointed in the direction where April and Casey were headed.
"Not to get hunted," April replied. "But we were looking for her. So, thanks for the help." April turned and began walking down the path that the boy indicated. "C'mon, Casey." Casey began to follow, giving a mock farewell wave before he turned. The girl phased into the ground, and then back up in front of April, as the boy flew over them and landed beside the girl.
"Are you trying to get yourselves killed?" she barked.
"No!" April cried. "We're trying to get her out of the city."
The girl leaned back slightly, surprised by her response. "Why?" She squinted her eyes in confusion.
"None. Of your. Business," Casey stated.
The girl paused a moment to think, "We want her out of the city too. But you two are going to get yourselves hurt. Or worse."
"We're already behind schedule," April sighed. "We have to get to her now."
"We're not letting you go," the girl told them. "Not alone."
"Fine," April hastily agreed, getting frustrated. "Just don't let her see you."
"Wouldn't dream of it," the boy mumbled, meaning what he said. The girl wrapped her arms around his shoulders and he floated towards the ceiling, keeping out of sight as they watched the other teens protectively.

...

Casey and April finally found the Hunter, with the masked teens still flying above. April held back for a moment, so she could give Don the location. The masked girl noticed, but was unable to hear what was said. April and Casey turned the corner, immediately alerting the hunter of their presence. "You!" Abigail bellowed, stomping towards the teens.
"Peace!" Casey shouted, raising his hands in surrender.
April rolled her eyes, "We want to help."
Abigail Finn stopped in front of the teens and gave them a suspicious glare. "What are you two up to?" she growled.
"Nothing," April lied. "Last night, we didn't realize you were the Dr. Abigail Finn. You see, we're monster hunters too. Amateur hunters, I mean. We thought you were just another hunter and we didn't want to give any information away to the competition. We were hoping you could help us. Or we could help you! It would be an honour to learn from you." April was playing her ego, hoping it was what the Doctor ordered. Dr. Abigail Finn arced an eye brow and the teens held their breath. "Amateur monster hunters, hm?" Abigail said, considering what she had been told. "Fantastic!" She threw her hands into the air, and wrapped them around April's and Casey's shoulders. "It's good to see young people getting into the art of monster hunting," Abigail added. "Now, if we're going to be hunting together, you need to tell me what you know."
"Not much more than you do, probably," April told her. "We read there were monsters down here and that some of them have been seen on the surface as well, nearby the forests."
"Interesting," Abigail commented.
Then they heard a loud roar. "The monster!" she cheered. "Quickly, children! This way!" The three of them ran through the tunnels towards the source of the sound. A few turns later, and they came across trashed walls and a series of damaged sorties.
"My sorties. They're useless now," Abigail whined. "Well, at least this means we're headed on the right track."
"Whoa, check out the claw marks," Casey noted. Abigail went over to where the kids were looking. Along the tunnel walls were several sets of claw marks. And they seemed to be going somewhere.
"We have something to follow!" Abigail shouted as she ran down the tunnel, with April and Casey behind her.

Kris and Kaitlyn were still flying above the others, and were currently wondering if Casey and April were luring the hunter into a trap, or if they really were hunting the monster with her. They heard another roar, this time quiet but close by. Kaitlyn had had enough. She indicated for her brother to fly ahead, and just before the hunter turned the corner, they dropped down in front of her.
"The hunt stops now," Kaitlyn bellowed. April frantically shook her head at the masked girl. Kaitlyn ignored her. She thrust out her hand towards Abigail, using her telekinesis to send her into the nearest wall with great force. Abigail became disoriented, and would stay down, but not for long. The teens heard scratching sounds coming from nearby, and Kaitlyn ran towards them, hoping to get the creature to safety.
"Wait!" April cried after her, but it was no use. The other teens ran after the masked girl. As Kaitlyn got closer to the scratching, she began to hear other people talking, and hoped they weren't more hunters.
"Dudes, she's coming!" said one of the voices. Kaitlyn rounded the corner and came to a dead stop. Standing before her were four anthropomorphic turtles, with multi-coloured masks and ancient-styled ninja weapons. And they were staring back at her.
