Sure enough, Schmeloise managed to open a portal back to Danville using a special device from her left hand. But...
"Hey, where's Perry?" Phineas asked.
As if on cue, a nearby TV showed Samy doing a news broadcast. "Attention fellow Miseryvillians," he said. "Lucius Heinous VII has announced the capture of what Surface-Dwellers call a 'platypus'. I repeat, Lucius Heinous VII has announced the capture of what Surface-Dwellers call a 'platypus'."
"Well, so much for that," Heloise told Phineas and Ferb. "You two should just head back to your world and act like he died of old age."
"We're not going anywhere without our platypus!" Phineas insisted. "He's a part of the family and we're not leaving him behind."
"Are you sure?" Schmeloise asked. "This portal won't stay open for long and I may not be able to open it again."
Suddenly, Candace accidentally fell in the portal after tripping over it, causing it to close.
"Hi Candace," Phineas said.
The 16-year-old girl got up and looked around. "Wh-Where am I?" she asked.
"Miseryville," Heloise answered. "A civilization located inside the Earth's inner core. Now we better get going before anything else happens."
After a while, Phineas, Ferb, Candace, Jimmy, Beezy, and The Miseryville Resistance (including The Protest Sisters) were riding on some train tracks in mining cars through a cave. Phineas already told Candace everything that just happened so far.
"Why exactly are we in mine cars?" Candace asked.
"Quick shortcut to where Lucius lives," Saffi explained. "He should be in the fourth building level."
Beezy looked at a map. "Hey, there's a snack bar in level five!" he said. "Can we go there if we have time?"
"So...are there any guys you like?" Candace asked Heloise.
"I can answer that for you," Schmeloise said. "Mistress Heloise has a soft spot for Jimmy, but ever since Lucius built Cerbo 3000, she has been obsessed with trying to defeat the evil dictator that she no longer cares about the boy she loves."
"Are you sure?" Candace asked. "Doesn't Heloise think Jimmy's cute anymore?"
"Negative," Schmeloise said. "All she cares about is protecting him from Lucius. She will do anything to make sure he does not receive more pain and torture."
"Really?" Jimmy asked, since he heard the entire conversation. "I would say that's nice of her to do that, but doesn't like being called that."
"We're here!" Saffi announced.
Sure enough, the group arrived at an entry way. "This is as far as we go," Heloise told Phineas, Ferb, and Candace. "Its your fight, not ours."
However, Jimmy approached the three siblings. "I refuse to let them be on their own," he told Heloise. "Us Surface-Dwellers need to stick together."
Heloise shrugged. "Fine by me," she said. And with that, she and the others got back on the mine cars and left.
"You're a Surface-Dweller?" Phineas asked Jimmy as the group walked in a dark room.
"I used to be one of you guys," Jimmy explained. "But that was before I saved an elderly lady from getting hit by a bus. Now I'm half-dead."
Suddenly, the lights came back on, revealing countless clown robots surrounding Phineas, Jimmy, Ferb, and Candace. Lucius and Doofenshmirtz arrived with Perry (who was in pet mode) in chains.
"Perry!" Phineas said. "We uh, well...well, we uh, came to rescue you! So far it's not going as well as we'd hoped. We didn't have time to, you know, plan something elaborate, but we could've, I don't know, created some sort of diversion, just in case..." He sighed. "Yeah, we could've thought this out more."
"All is going according to plan, Heinz," Lucius said. "Now that 'The Hero of Light' and his friends have been captured, nothing can stop us from taking over the surface world!"
Doofenshmirtz checked a watch. "Can we do it tomorrow?" he asked Lucius. "It's 3:40, which is awfully late for us to start the invasion today."
"I guess you're right," Lucius replied. "The robots look like they're running out of energy."
"But we could always get the Other-Dimension-inator ready for tomorrow," Doofenshmirtz pointed out.
"Brilliant idea, Heinz," Lucius said, then he approached Phineas as a clown robot brought in the device.
"What do you want from me?" Phineas asked.
"I want you to fix this machine," Lucius responded. "Or I will make you suffer."
"Do your worse," Phineas said. "You may take my life, but you'll never take my freedom!"
"Phineas, I don't think now's the good time to quote Braveheart," Ferb said.
"Hold on a minute," Doofenshmirtz told Lucius. "I just remember what allowed this to work! They just took out the self-destruct button."
"Excellent work, Heinz," Lucius said. "I guess I don't need the Surface-Dwellers anymore. Guards, send them to the basement!"
