Hey! Sorry if this chapter is a little late, but I hope you'll like it.

Before I start, I would like to thank Gamelover41592, Lucy Case and Danielle Domain for their awesome reviews. And, Blaze is Daniel for his favorite. Thank you all and God bless!

Begging for his nemesis to join him on his search for the criminal is easier than he thought. He just sang a whole song about his plan and it took two minutes for Perry to think about it. Fortunately, the Platypus nodded as an approval, which made the evil scientist wear an evil—or at least—happy grin on his face, and went outside to start their search. However, they would have to settle for who will get the money since they want (Doofenshmirtz and Major Monogram) or needed it. Now, Doof—who is dressed like Sherlock Holmes—and his partner—or nemesis—Perry are walking on the pavement to gather all the pieces of the puzzle.

"So far the only clues we have are these," Heinz took out a small notebook in his pocket, flip the cover and reads it. "The criminal carries a diamond-shaped knife; Based on the crime video, he has unusual skills which is different from a regular martial arts like Judo and Karate; Based on the police officers, he is tall and has a spiky hair." He shifted his gaze on Perry, who looks like he's trying to gather all the pieces of the puzzle, and puts his notebook back in his pocket. "Any ideas?"

Perry closed his eyes and crossed his arms. This is hard. Despite that they already gathered four clues, it doesn't make sense. "Grrr….." Perry slowly shook his head.

"Well… I have to admit, this crime is really tough to solve." He said with a tone of despair. "Anyway, let's keep looking. I'm sure that we're 98% close in solving the mystery."

Perry opened his eyes and looks at his nemesis. Judging by the expressions in his eyes, he's really determined to solve this crime despite that it's a good thing. Although, it's still a part of his plan, but they'll have to deal with that after solving the crime.

"Come on Perry the crime-investigator-pus, let's solve that mystery and get the—"

"Out of the way!"

Doof and Perry turn their gazes to wherever that voice is coming from. They saw a tall kid—about 16 years old—who is wearing a black and orange jacket, black sandals, an orange pants, a black headband and has a spiky-blond hair.

"Out of the way!" He yelled again, but the two are not moving an inch. Darn it! Just please, move.

"Hey you! Don't let the criminal get away!" The mob yelled.

Doof and Perry's jaws drop. He is the criminal? But that's impossible, he's so young! Nevertheless, who would have thought that solving this crime will be as simple as frying eggs and bacon?

"Is…. Is he really the criminal?" Doof asked hesitantly while Perry shrugged.

"Don't just stand there! Do something or we'll lose the money!" One from the mob yelled.

Doof shook his head. What was he thinking? The mob's right! If they would just stand there hesitating, they would lose their price, and he will not let that happen. "Let's get him, Dr. Watson." Doof said determinedly and went on his fighting stance.

Perry tucked his fedora, "Grrr…." He smirked and runs toward Naruto.

What the?! Naruto quickly stopped at his tracks—and so as the mob. Th-That animal, i-it looks…. Kinda familiar…. He said to himself as he observes the Platypus running toward him.

"Go get him, Perry!" Doof cheered.

Perry? Naruto thought. Could it be? Is it really Phineas and Ferb's pet? If it were their pet, then why it is standing like a human? Shouldn't it be home, sleeping? And he thought that Platypuses don't do much.

Perry jumps in the air and moves his right arm forward, with his fist clenched, to punch him. However, seeing what the Platypus is doing, Naruto quickly used his right palm to block its punch.

Perry's punch created a collision that almost made the clone stumble or disappear.

Darn it! Naruto thought as he holds Perry's punch. Since when did animals in this world know how to fight?

Perry gave him a puzzeled look. That's strange. He's expecting that the 'criminal' will stab or punch him away just like he did on those teenagers. Moreover, this blond guy looks kinda familiar. Haven't I seen you before? Perry mentally asked as he scans the blond's face. Cat-like whiskers, bright blue eyes like the ocean, spiky-blond hair and the same symbol that Hinata has on her headband which she wears around her neck. What the?! Perry quickly removed his fist on Naruto's palm and jumps away from him.

Naruto, Doofenshmirtz and the mob gave Perry a confused look.

"Why did he do that?" The mob murmured.

Perry moved his left foot backward. Is that you…. Naruto?`

Flashback:

Perry sighed. He's glad that Doofenshmirtz's Alliance-Inator failed on finding an evil person. And the best part is, she even helped him thwart Doofenshmirtz's plan. He made a mental note that he has to thank her, if they see each other again. Perry scans the Flynn-Fletchers' backyard and found a safe place to land. 'I guess the boys' daily activity has already finished.' Perry thought and landed in front of the back door. He deactivated his jet pack and returned in his pet mode. 'Yes, I can finally—'

The door creaked open revealing a tall guy with a spiky—or messy blond hair wearing an unzipped jacket and orange pants, holding a garbage bag and walks away from the door not noticing the Platypus in front of him.

"Ow!" The blond tripped and fell on the ground.

'Rest.' Perry continued and gave him a suspicious look. 'A relative?'

"Hey Naruto," The boys peered behind the wall.

"I told you to throw that garbage somewhere!" Candace yelled furiously and peered behind the wall.

"I was gonna," Naruto rubbed his head and stood up. "but I tripped on something."

"Tha—"

"Whatever just do it!" She said and went back to the kitchen.

"That went well." Phineas said.

"Actually, you didn't tripped on something." Ferb smirked and points on the floor while the two just followed his finger.

"Grrr…."

"Oh there you are Perry." Phineas stepped outside and crouched beside their pet.

"A….. duck?" Naruto asked. 'A really weird duck'

The brothers furrowed their eyebrows.

"Actually, he's a Platypus. He doesn't do much." Phineas said as he caressed its head. "Perry," Phineas grabs Perry and shows it to Naruto. "meet Naruto."

"Grrr…"

"Hey!" Naruto grinned and stroke is head.

End of Flashback….

Perry clenched his teeth. It is Naruto! And he knows that Naruto is not the criminal. He's a good guy, he tolerates Perry like he's his own pet. Moreover, he has the same symbol that Hinata has on her headband and he also did not stab or punch him. But what really scares Perry, is the fact that Naruto has seen him in his secret agent mode. Plus, he knows his owners. Damn it! Not only he's from another dimension but he also knows Phineas! What should I do?! I don't want to be relocated!

"Perry the Platypus, are you hesitating to fight him?" Doof asked as he saw his nemesis' hand is shuddering.

"Perry… the… Platypus…." Naruto muttered. Is it really the Flynn-Fletchers' pet?

With the gang...

Seeing the mob in front of them, the gang quickly stopped at their tracks and pants for a while.

"Awesome job, Hanabi. We finally caught them." Phineas said and finds Naruto. Darn it! I can't see anything from behind!

"Actually," Hanabi closed her eyes and deactivated he Byakugan. "I'm not sure if it is Naruto."

Candace stops panting and rose an eyebrow, "What exactly do you mean by that?" She asked curiously.

Hanabi opened her eyes and looks at Candace. "Naruto has activated some clones, and I can't figure out which is the real one; Therefore, I chose to follow the closest one."

Candace face-palmed. Great, just great. Now how will they find out which is the real one?

Hanabi sweat dropped. "Everything okay, Candace-san?"

Candace sighs, "Nothing." She said.

"It doesn't matter," Phineas said with determination in his eyes, "we have to help him whether it's a clone or not." He walked briskly and huddled through the mob.

"Great, there he goes." Candace said as they observe Phineas huddle through the mob.

"Should we help him?" Isabella asked.

"Probably not," Ferb shrugged. "Phineas can do it."

...

"Hey Naruto." Phineas used his hand to move someone's leg out-of-the-way. "we're—"

Seeing the situation, Phineas' eyes widened in shock. Naruto is standing meters away from him on the Northwest side and on his north side is a man—who looks really familiar, but he can't put a finger on it—about 48 years old wearing a Sherlock Holmes outfit. Although, what really shock him is the Platypus in front of Naruto wearing a fedora.

"P-Perry?"

`that's the part where I forgot and failed to do on Chapter 11 (Family Time).

It's really hard doing this, and yeah, I know I said "a glimpse of a Platypus in a fedora", but I failed on the glimpse part. Don't worry, the others won't know about this, Phineas is he only one who knows about this.

If you got some suggestions, I'm all ears.

So, I hope you like it and God bless.
