"WE'VE BEEN HIT!", Phineas exclaimed.

The water balloon smacked him square in the face and caused him to fall over as the tree house he and Ferb were in was under attack by Buford and Baljeet from the other house. Phineas got back up on his feet and held out a toy sword towards his opponents.

"Retaliation!", he ordered.

Ferb gave a salute and launched the catapult next to him, causing bunches of water balloons to go flying out at the other tree house.

"They are attacking!", Baljeet exclaimed. "We must take cover!"

Buford quickly did what he thought best and grabbed the nerd and held him up as a shield.

"Aah! I did not mean me!", Baljeet complained before getting pelted with water.

Buford soon sat him back down and pointed to the other side of the tree house.

"Go load the catapult and secure the princess.", he ordered, making Baljeet do so.

"Help me my hero!", Isabella played along with a wide smile as she looked down at Phineas from her higher branch.

"I'm coming my fair lady!", Phineas joked as he climbed up through the branches.

He dodged over a couple of water balloons and was just a few inches away from Isabella's outstretched hand when he suddenly got hit in the head and fell over out of the tree. He face-planted into the ground and tried to pull himself up.

"Phineas!", Isabella shouted before grabbing a random vine nearby and swinging down to help him while everyone else climbed down.

She was the first one to reach him and help pull him out of the ground.

"Are you okay?", she asked.

Phineas coughed and sputtered and wiped the dirt from his face.

"Ugh! Ulgh, no. I'm okay but I got dirt up my nose.", he said nasally.

"Ha ha! You dweeb! Only you could have a big enough nose to get dirt shoved up in it!", Buford teased as Ferb came over.

Ferb handed him a handkerchief and Phineas blew out the dirt. That's when everyone else noticed something on the back of Phineas' head. Phineas groaned a bit, unaware of everyone staring at his head and finally got the dirt off before looking back to hand Ferb his handkerchief.

"Thanks Ferb.", he said.

He then noticed the stares and looked about the group.

"...What?", he asked, feeling a little unsure. "Do I still have some dirt on my face or something?"

"Uh.. Phineas? Have you been to a...tattoo parlor recently?", Baljeet asked.

"Nnoo...", Phineas replied, completely bewildered.

"Been playing with markers?", Isabella suggested.

"No. Not on my body.", Phineas said. "Why?"

"Uh.. Cause you've uh.. You got this...", Isabella tried to explained, unsure of how to describe it.

Ferb turned him around and took a digital picture. Phineas turned back around and everyone looked over to get a better view of what it was.

"It.. It's a date.", Phineas said. "On the back of my head?"

"Apparently", Baljeet shrugged.

"A date? What you're seeing someone, Phineas?", Buford asked.

"No.", Phineas shook his head. "I don't have any real plans in the next... Three days."

"Hmm.. It kinda looks like the expiration date on the cans of food my mom buys at the store.", Isabella noted.

"An expiration date? Really? That's impossible.", Baljeet waved a hand uncaring. "People don't just HAVE a date on the back of their heads saying when they're gonna 'expire'."

"I'm just saying, that's what it looks like.", she shrugged.

"Wh-what if it IS?", Phineas said, feeling a little nervous now.

"It is impossible!", Baljeet argued. "Sorry but you guys are being ridiculous! People do not KNOW when they are going to die!"

"Y'know my grandmother had a birthmark that looked like a date.", Buford remarked.

"Yes, but did she DIE on that day?", Baljeet asked.

"Yup.", Buford simply said.

Everyone stared at him wide eyed and then Phineas was more than ready to begin to panic. They looked back at him, equally worried.

"Uh...", Isabella began.

"N-no! I-I-! I can't! I'm- I'm only ten for crying out loud!", Phineas said as fear clutched at him.

"Uh-oh. Denial.", Buford noted. "First in the 5 steps of dieing."

"You're NOT helping!", Phineas growled, holding up a fist, wanting to choke him.

"Wasn't the next stage anger?", Buford teased.

As they fought, Ferb walked into the garage. Their argument was interrupted by loud banging and whirring and the sound of flames whooshing. Soon he came back out with a small scanner and turned Phineas around.

"Ferb? What are you..?", Phineas asked.

The scanner finally finished and Ferb looked at the result but his eyes became wide. Isabella and everyone looked over his shoulder and were equally worried. Phineas looked around at his friends and became worried himself at their nervous expressions.

"What?", Phineas asked. "What? What does it say?"

Ferb was hesitant at first but after a moment reluctantly gave the scanner over to his step brother. Phineas took it and looked over the findings. His eyes became wide as he took a step back.

"Wh-what?", he said in a half whisper. "This... This can't... No! M- Th- It's impossible! My molecules can't be decaying that fast!"

He dropped the scanner and back up, still staring at it in horror. He looked back up at his friends who only stared back hopelessly. He shook his head, trying to grasp the idea in his head.

"I'm... I'm gonna die in three days?"
