After what seemed like hours of searching, the gang found a small house between two large craters.
"This is where Jimmy lives," Nala told Phineas and Ferb. "This is as far as we can go. You two are on your own from this point forward."
"Thanks for the help," Phineas said. "I hope we see you again soon."
"Don't worry," Gnaw said. "You will." Then she, Nala, Gust, Warroir, and Lucky vanished thanks to their teleporter.
Phineas and Ferb walked up to the house with Perry (who was still in pet mode the whole time) following them. Phineas knocked on the door.
"Who is it?" a voice from inside asked.
"Someone who needs help from Jimmy," Phineas replied.
The door opened, revealing a large red demon. "You're both Surface-Dwellers," he said. "And that strange creature must also be from the surface world. Come on in."
Phineas, Ferb, and Perry walked inside. "Is Jimmy home?" Phineas asked.
"He hasn't left this place for a month," the demon explained. "My name's Beezy, by the way. Jimmy's upstairs in his room."
Beezy opened a door, revealing a dark room. "Jimmy, these two Surface-Dwellers want to see you," the demon said.
The lights were turned on, revealing a horrible sight. The word HELP was written in red all over the walls. A fourteen-year-old boy was using paint to write another HELP on a blank spot. He was so pale that he was almost white. His blonde hair was disheveled with long bangs hanging in front of his amber eyes. His light green t-shirt and blue jeans were ripped, exposing his newly-developed muscles. He was barefooted and there was a black and dark purple manhole cover chained to his left ankle.
Phineas was shocked. "YOU'RE Jimmy Two-Shoes?" he asked in alarm. "You don't look happy like that video in the dumpster described."
Jimmy slowly walked over to a plate that contained several butterscotch-dipped pickles. "That was before Lucius became power-obsessed," he said in a quiet voice. "He chained the Bad Luck Accelerometer to me, put me on house arrest for life, and forced me to eat nothing but pickles dipped in butterscotch."
"He hates butterscotch and he's afraid of pickles," Beezy explained.
"How did you two Surface-Dwellers get here?" Jimmy asked as he ate a butterscotch-dipped pickle.
"We used a portal," Phineas said. "Although I'm not sure why everyone here keeps on using the term 'Surface-Dwellers'. Isn't this an alien planet?"
"Where did you get that from?" Beezy asked. "Miseryville's inside the Earth's inner core."
"You mean we've been INSIDE Earth the whole time?" Phineas asked.
"At least that would explain why everyone here speaks English," Ferb pointed out.
"So what happened to you two?" Beezy asked the two stepbrothers. "You look like you came across dad's new pet."
"Actually, we came across Cerbo 3000," Phineas explained.
"Phineas, I think what Beezy's trying to say is that Lucius is his father," Ferb said.
"Can't you overthrow him?" Phineas asked Beezy.
"Dude, he's my dad," Beezy pointed out. "I'm not heartless enough to freeze him with the others in my family."
"So you're going to let him get away with THIS?" Phineas asked, referring to Jimmy. "He used to be the guy who can never be broken!"
"I would be able to deal with this stuff," Jimmy explained. "But that was before Cerbee disappeared. Things haven't been the same since then."
"Guys, what are you talking about?" a petite fourteen-year-old girl asked as she entered the room. Her eyes widened as she noticed Phineas, Ferb, and Perry. "Are those...Surface-Dwellers?" she asked.
"Yes, yes we are," Phineas answered.
"Okay..." the girl said, then she left the room, confused with what she saw.
"That was Heloise," Beezy told Phineas and Ferb. "She and I have been living here since dad blew up our houses. All that's left of them are two large craters."
"So what do you two around here for fun?" Phineas asked.
"I work on my room," Jimmy said, referring to the red paint on the walls.
"But it's summer," Phineas explained. "You could always go to a water park if there's one here."
"'Summer'?" Beezy asked in shock. "What kind of a word is that?"
"I remember summer," Jimmy said as he took out a guitar. He started to play an unknown tune. "I even wrote a song about it since it doesn't exist in Miseryville."
Jimmy: Summer is running through the sprinklers in your T-shirt, shoes, and jeans
Rolling down a grassy hill, yeah, that's what summer means to me
It's true
There's so much more to do
Phineas: The days are longer
The nights are shorter
The sun is shining
Ferb: It's noticeably warmer
Phineas: Summer, every single moment is worth its weight in gold
Summer, it's like the world's best story and it's waiting to be told
It's ice cream cones and cherry soda dripping down your chin
It's summer, man, where do we begin?
Jimmy: Summer is ponds and pools and garden hoses, tryin' to beat the heat
Summer, bicycles and roller skates and even just bare feet
It's also...
Phineas: *interrupts Jimmy* Surfing tidal waves, creating nanobots
Or locating Frankenstein's brain
Finding a dodo bird, painting a continent
Or driving our sister in-
Oh, wait. Maybe we're going too fast.
Jimmy: Summer, it's crickets and cicadas and a glass of lemonade
Phineas: Summer, it's sitting with your brother in the backyard under the shade of a big tree
That's what it means to me
The days are longer
Phineas and Jimmy: The nights are shorter
The sun is shining
Ferb: It's noticeably warmer
Phineas: Summer, every single moment is worth its weight in gold
Summer, it's like the world's best story and it's waiting to be told
It's ice cream cones and cherry soda dripping down your chin
It's summer, man, where do we begin?
Jimmy: It's summer, man, where do we begin?
Phineas: It's summer, man, where do we begin?
As Phineas was talking about what he and Ferb did during the summer, Perry headed for the TV downstairs, still in pet mode. Lucius was on a news report. "This is a message for Perry the Platypus," he said. "And no, you can't fool me with your disguise. If you don't turn yourself in, I will have Cerbo 3000 come after your Surface-Dweller friends."
Perry then quietly walked out of the house. He got back on his feet and put his fedora on. After a quick glance and Phineas and Ferb (who were unaware of his absence), Perry sadly walked over to Lucius' house.
I walk away
From you my friend
I hope that this
Is not the end
Of all the times we figured out
How to seize the day
And I walk away
