DISCLAIMER TIME! I do not own Hey Arnold, which belong to Viacom, Nickelodeon and Craig Bartlett!

Since my last Nicktoon one-shot with Hey Arnold got taken down, I decided to make a brand new one in its' place, basically with the same plotline, but with no song sequence. Anyway, I hope you enjoy this fic!

At the park, Helga was busy sighing over her locket of Arnold as she was smiling to herself. Over the course of the years, Helga always loved Arnold, but her curiosity often peaked about the boy she loved. What was his family like, why did he have a head shaped like a football? Not that she didn't like Arnold's head, but it was pretty... peculiar.

"Helga?"

Helga yelped as she quickly pocketed the locket, fearing somebody saw her... to her relief, it was only Phoebe, but she had to be careful regardless. "Oh, hey, Pheebs."

"Helga, could you come over here and help me explain to Rhonda and Nadine about something?" Phoebe asked. "Rhonda and Nadine wanted to know about Arnold's family history, and since you seem to know a bit about Arnold, they want to know what your take on his family history is."

Helga raised an eyebrow in curiosity. So, Nadine and Rhonda were thinking about the same theory, hm? This had to be interesting. "And why would Rhonda and Nadine care about my opinion? For that matter, why don't they go to Football Head himself?"

"They're not sure how to approach him without hurting his feelings. They know Arnold's parents aren't... around him these days." Phoebe said. "Please, Helga?"

Helga paused... then sighed. "All right, Pheebs, I'll do it... and Phoebe, bring the theory charts we were making on Arnold for a while."

"Bringing!" Phoebe said in her adorable voice.

Pretty soon, Rhonda, Nadine, Phoebe and Helga were together as Nadine coughed. "Okay, Helga, this is just a personal question Rhonda and I wanted to ask."

"Do you think we can ever see Arnold's parents and what they look like?" Rhonda asked. "I just thought it would be nice..."

Helga paused as she looked at the family tree plans. "I don't really know for sure, I'm not Arnold's keeper... but yeah, I am really curious to know about his parents."

"So, you say you have a theory?" Rhonda asked.

Helga smirked. "Indeed. I think that Arnold's family tree was around long before the Revolutionary War."

"Ah... yes, the time of Washington and the Declaration of Independence." Phoebe smiled as Rhonda and Nadine leaned closer.

"Eventually, the family survived pretty well into the Civil War, but then they started to branch out a little." Helga explained. "As we've heard from Arnoldo's grandfather's stories, back in the twenties, Arnold's grandfather lived as a kid... hard to believe that he actually lived this long."

"You said it." Rhonda nodded. "As crazy as he and Arnold's grandmother is, they are pretty enduring in their own way."

"Well, I believe that Arnold's family came from a long, LONG history of his head shape!" Helga smirked. "Notice the football head on Arnold? Notice how everybody else has good heads? Well, during the Civil War, one of Arnold's relatives suffered a blow to the head with a cannonball, which caused his head to be slightly deformed. If you take a look towards the right..."

Rhonda and Nadine then just blinked as Helga kept pointing out football head similarities as they both sighed. Nadine said, "Okay, Helga, just stop right there, just...stop."

"What?" Helga asked in confusion.

"Helga, if you're not going to take this seriously, just say so." Rhonda sighed.

"Aw, come on, Rhonda, you know it has to be true... how else would Arnold have a head shaped like a football?" Helga said. "You ever think of that, princess?"

Rhonda frowned as Phoebe shook her head, Rhonda saying, "I have a feeling you just wanted to insult Arnold the minute we asked you the question... you were totally leading in to a moment where you were about to insult Arnold, weren't you?"

Helga frowned as she rolled her eyes. Phoebe looked over to Helga as she asked, "Is it true, Helga?"

Helga sighed. "Okay, so what if it is? But my theory still stands, AND at least I had the guts to bring it up!" Helga said as she got up and started to walk off. "Honestly, it's just a theory... a Football Head theory!"

Rhonda and Nadine shook their heads as Rhonda said, "I will never understand why you and her are friends, Phoebe..."

"It's a complicated story..." Phoebe said, blushing a little bit.

"Well, whatever. Want to hang with us for a while?" Nadine asked. "We need a little help."

"Sure." Phoebe smiled as she followed the two off.

As Helga watched the three go off, she just rolled her eyes as she talked to herself, "The very idea, making a wild theory on Arnold..."

Helga then sighed in lovesickness as she pulled out her locket of Arnold. "Well, I don't know how much of it is true, my angel, but I hope I learn your true story some day..."

Helga then started happily skipping for a while (only stopping when she overheard Arnold and Gerald talking and coming near her direction a few minutes later as she went back to her normal stance.)

And that is this Nicktoon one-shot out of the way! How was it? Anyway, next Nicktoon one-shot will be on the way! Keep your eye out! Anyway, read, review, criticize and suggest, folks!
