Act 1 (All setting is set in the Second Dimension or 2D)

-Everburn Forest, 11:50AM-

At Everburn Forest, Team Dinopals, Ferb, Perry, and Dr. Doofenshmirtz finally set foot on the Second Dimension Great Valley. They may not find Phineas and Isabella but they can actually smell their presence here. With Chomper on the band, they can find them without a stop on them

"I can smell, Phineas and Isabella crashed into these leafless trees in Everburn Forest" Chomper sniffed the crash site while Ruby, Ducky, and Petrie scan for evidences

"Why would they call it a forest if they are no leafy trees?" Dr. Doofenshmirtz asked in curiosity to Littlefoot

"Because its abundance is geothermal obstacle known as lava" Littlefoot said while he felt his feet tremble on the ground "Earthshake!" and suddenly, a lava spew out of the three's zone as everyone dodged the lava geyser

"That time, you overshot the lava fumes" Terra mildly complained
"I can't smell lava fumes" Chomper replied while he sniffed their scent somewhere off-the-area "They were here and later sent into southwards"

"There must be Headquarters for them somewhere" Ruby hoped while she read the map "Betcha the map can help us find them. In south of our starting point, it's Doof Rebellions Headquarters" the team (Including Perry, Dr. Doofenshmirtz, and Ferb) exit the forest and travel to the headquarters to find Phineas and Isabella but they were stopped when someone saw a Golden glow in the distance

"Guys, I see something in the distance" Ducky said in unison, paying attention to her "It's the Golden Weapons. Some other team will get Phineas and Isabella for us, don't worry about it"

"Come on, Furiza" Terra grumbled "You won't be hiding any longer now" everyone chased the Golden glow in the distance as the Golden Weapon scheme will almost be thwarted by them

-Doof Rebellions, 11:55AM-

After they discovered Isabella's Timeline Spoiler, Terra-2 is surprised that their next target may be her. Unaware of Phineas, he knew how she got the ability of Timeline Spoiler

"Lagot tayo" Terra-2 disappointingly said "Si Dr. Doofenshmirtz ay hinahanap si Isabella. Siya ay meron ng Timeline Spoiler; Sa abilidad na yan, kaya na siya magtatanong ng nakaraan, ngayon, at bukas" everyone gasped as Isabella tried to explain

"I can explain, everyone" Isabella pleaded to listen her "I got the ability when Phineas and I first visit the Great Valley. I hope you understand and please don't lock me up"

"We understand, Isabella" Ruby-2 understood while the alliance agreed "Chomper of the Second Dimension used to have a Timeline Spoiler like you"

"Is that why Chomper is dead or missing?" Phineas asked

"So far, status is unknown" Ali-2 replied while she pressed a button to call off 'Pause Viewer Now' "But Enigma Lavascope, this would be the answer for all of us" the screen unpaused 2D Dr. Doofenshmirtz' video as it reveals that he and Furiza are at a grassfield with a volcano in the distance

"So, have you found the answer?" 2D Dr. Doof said the answer "It's Enigma Lavascope. This place is where Furiza and I will merge the Golden Weapons into an Omega Weapon"

"That's right, and you can't do anything without Team Dinopals" Furiza said while showing off her Golden Weapons to the alliance "Once we merge it into an Omega Weapon, we will take over the Great Valley today, and the whole world by tomorrow"

"Nothing can stop us now!" 2D Dr. Doofenshmitz exclaimed evilly as they all laugh evilly so evil and maniacally that the footage ends in five seconds

"Oh, great" Petrie-2 annoyingly scoffed "What a laugh of mockery"

"Looks like we're going into adventure phase, Doof Rebellions" Littlefoot-2 stomped the floor in reluctance, setting up a plan "Now, here's the plan. Ruby" the pink fast-runner rolled her eyes in agreement as she flicked a button to show the monitor the plan in blueprints

"Okay, Littlefoot's plan is to summon our team and Two Phineas, Second Dimension Ferb, and Two Isabellas into Enigma Lavascope" Ruby-2 demonstrated the plan "We're needing an optimist on this mission so we recommend Phineas in the mission, a technician which is Ferb, and a heroine for Isabella"

"Candace and the Resistance, guard the Headquarters" Cera-2 said while they prepare for transportation "We don't want any Normbots attacking our base. Turrets are provided in this area"

"Aye aye, Cera" Candace-2 saluted in agreement

"Our mission is to head to the underground of Enigma Lavascope via the Resistance's newly-built minecart and railways" Littlefoot-2 said while the monitor displaying the simulation through 2D animation engine "Since Ferb has the map of the railways, he will guide us into the underground and head to the heart of the volcano and-"

"Wait, did you say volcano?" Petrie-2 interuppted in fear

"Opo, bulkan" Terra-2 answered "Ito'y puno ng kumukulong putik sa ilalim ng lupa"

"What if we got melt by them?" Petrie-2 asked

"Technically, we're only using minecarts on the way. We are, we are" Ducky-2, beside Petrie-2, said "We're only using the railways to guide into the heart of the volcano and we'll be fine on the way"

"Another plan is if we do lose our minecarts, we can use the electrical spinning tops of doom from Phineas and Ferb's Phineas and Ferb-Busters!" Ali-2 told about the alternate plan "They already hid it somewhere underground and we can use as our getaway from Dr. Doofenshmirtz' army if the plan fails for us"

"Oh, me get it" Petrie-2 understood already "We hope we get the Golden Weapons fast"

"Set up the minecarts, the Resistance" Littlefoot-2 said as he declared to the dual dimensions Phineas and Isabella "Welcome to Team Phineas, Phineas, Ferb, and Isabella of the Second Dimension" Doof Rebellions head into the lobby to prepare the minecarts as the Resistance saluted goodbye to Phineas, Ferb, and Isabella so they can meet each other with their alternate dimension counterparts

"Okay, welcome to the team, guys" Phineas confidently greeted to his second dimension self

"You mean two us" Phineas-2 said "Looks like the mission is going to be tough"

"Guys, I know what we're going to do today" Isabella-2 used Phineas' catchphrase in her usual sassy way

"We're gonna get the Golden Weapons before Furiza merge it into the Omega Weapon" Isabella said in her uprising mood

"Let's go, team!" Phineas exclaimed in unison as he leads the team into the same lobby Doof Rebellions are heading to, the Resistance prepare for their defenses with the Doof Rebellions as their exploration to Enigma Lavascope will begin shortly

-Enigma Lavascope-

Enigma Lavascope is an active volcano exclusive to the Second Dimension Great Valley. It erupts monthly as the valley's climate is in unstable condition due to 2D Dr. Doofenshmirtz' destruction. It is almost as high as and as it look like as Mount Mayon in the Philippines and is known to be an active stratovolcano in the Great Valley

-Enigma Entrance, 12:00PM-

At the entrance of the underground, Team Dinopals, Ferb, Perry, and Dr. Doofenshmirtz are lead by the Golden Weapon's light. They must've been tired along the way because of exploring Everburn Forest is annoying as heck

"There it is, Enigma Lavascope" Terra introduced the active volcano in the Great Valley

"Sure this will make us lost in battle here" Ruby said in curiosity until she touched her foot into a weird carpet "Don't mean to brag but what's with those electrical carpets?"

"Probably, there may be any spinning tops that Phineas and I invented" Ferb said in a suspicious mood "But I have no idea how it is invented here and somehow placed it under a hot and steamy underground"

"I don't need to interrupt but you gotta see this" Dr. Doofenshmirtz said in unison to everyone, they followed him and they found something at the other side of the entrance

They've found 2D Dr. Doofenshmirtz' base where Furiza and Dr. Doofenshmirtz are preparing for exploration at the cave with their alternate entrance. They clone thirty Normbots to assist them while twenty more to guard the base itself

"The other side has the other dimension Dr. Doofenshmirtz' base" Chomper said indifferently "Looks like they've gone for a head start for Furiza. By the way, it's lunch time"

"Yeah, but we remember that we ate along the way" Ruby replied to his indifference, the team slowly get away from the base as they enter their only safe entrance

"By any lawful means, we have to explore inside the underground and get the Golden Weapons from Furiza" Terra said while sheathing his map from his hand, pointing to Dr. Doof "And you're going to help us, Dr. Doofenshmirtz"

"What? No way I'm helping you" Dr. Doofenshmirtz declined arguably "Even if it means that I'm no villain in this finale, no way I'm falling for your tricks" ignoring his decline, Ali lead the team to the underground anyway

"Let's go, Dinopals. Ali will show us the way" Littlefoot said in unison "Team Dinopals Roll!"

"Seriously, is anyone listening to me?" Dr. Doofenshmirtz asked to pay attention but Ferb and Perry go beside him to say

"We heard you but we're in a rush to find my brother and Isabella" Ferb said "Also, Furiza is heading to the finale way better than us if you don't help them"

"That I understand" Dr. Doofenshmirtz said defiantly "Come on, I'm helping them anyway" Dr. Doofenshmirtz then follow Team Dinopals and lead Ferb and Perry to the cave

"I hope you better be, Dr. Doofenshmirtz" Ferb said before changing the scene "Because Furiza disbanded you after getting the Golden Weapons"

-Enigma Underground, 12:05PM-

At the underground of the active stratovolcano in the Great Valley, Team Dinopals, Phineas, Ferb, and Isabella are riding on the minecarts with Terra as the driver of the rails. From Littlefoot and Terra to Dual-Dimension Phineas, they all share together in two people per cart

"Okay, we're below the lava surface of the underground" Littlefoot gave a quick tour of the underground "So we will see lava falls along the way" Ali and Ruby share the cart together as they formulated the plan

"When we reach the centre of the volcano," Ali formulated the plan "Known as Enigma Centre, we will set up a trap for Dr. Doofenshmirtz and Furiza to fall for" everyone listen the team plan while Dual-Dimension Isabella are having a little chat

"Essentially, why should I stay beside you?" Isabella asked in curiosity "Are like sharing carts in a friendly way?"

"It's very oblivious if you say that but yeah, I think so" Isabella-2 replied indifferently "Do you Phineas is acting weird when he approached me?" Isabella turned to Phineas and his second dimension self

"I'm pretty sure he has a crush on you" Isabella said with a smirk "I bet you have feelings for him, right?"

"What? I do like him only as a friend" Isabella-2 blushed "Why you? Do you like him more than a friend?"

"Well, I like Phineas while the other dimension Phineas like you" Isabella said about different personalities in different dimension "So, it's a mirror fact in parallel universe" Isabella-2 shushed her and they continue to listen Doof Rebellion's plans

"Once we steal the Golden Weapons from Furiza, this will be our another team's cue" Ducky-2 continued the briefing "A team named Team Dinopals will be on their way and they have to race outside the underground and head to the top of the volcano which is known as Enigma's Heart alongside the lava flows or lahar flows known as Lavascope Pit. Are we all clear?"

"Yes, Ducky" Everyone exclaimed as they saw a sign reading '1km to Enigma Centre'

"Isa pang kilometro at nandito na tayo sa Enigma Centre" Terra-2 announced

"Thanks, Terra" Ruby-2 thanked him as they pass the lava lake

While on the way to Enigma Centre, Phineas turned to his Second Dimension Self who has a rose still in his hand. It reminded him of planning to give a rose to Isabella on Valentine's Day. He still has feelings for Isabella even though he is more oblivious than noticeable for her

"So do you get to spend time with Isabella?" Phineas asked

"What do you mean?" Phineas-2 asked in confusion

"She said you're supposed to give a rose to Isabella" Phineas heard what Isabella saw earlier "But my dimension Isabella chicken out and you two felt awkward after she left"

"Well, it's just… Isabella and I didn't get to hang out together even after Dr. Doofenshmirtz' temporary arrest" Phineas-2 explained "We were at different classes and she tends to be falling out from me"

"Phineas, Isabella won't fall out from you" Phineas said to his other dimension self "Whether you have skills or not, she will still like you as a friend"

"More than a friend?"

"Considerably"

"Well, why do you get along with Isabella so easily?"

"She is the leader of the Fireside Girls Troop 46231" Phineas said his thoughts about Isabella "She is also similar to me by personality and alway feminine through her cuteness"

"Phineas, my Isabella isn't that cute at all" Phineas-2 said his thoughts about Isabella-2 "She is alway self-thinking and well always busy at her missions back at the Resistance. She is also fashionable so she always watches me and my fashion odds"

"If I were you, Isabella will accept you as a friend" Phineas understood as he gave an advice "But if you more than a friend, she will be your best friend and someday become crushes. For me, I have feelings for her. I just have to be oblivious because we're too young to start a relationship" suddenly, Isabella popped out of the last cart or the caboose which she is in front of Both Phineas

"Aww, thanks Phineas" Isabella complimented while both Phineas are surprised of her

"Isabella, qué estás haciendo aquí?" Phineas asked in shock but their chat is short-lived when Terra-2 announced

"Doof Rebellions, malapit na tayo sa Enigma Centre. Ihanda ang mga sandata bilang sa kulang na tayo nang riles" Oblivious to everyone, Phineas defiantly looked at her for hiding reasons

"Phineas, other dimension Isabella bet me to check on you privately" Isabella honestly said "That is all" the minecarts have into an abrupt stop by Terra-2 slowing down the carts through his Earth Elemental Powers, it is stopped by a cart stopper as Doof Rebellions dock out of the minecarts

"Well, we should get going" Phineas said to everyone while he turned to Isabella to inform "Please, Isabella. Team Dinopals will be on their way" the rest of his team also dock out of the minecarts to follow Doof Rebellion's trail

-Enigma Centre, 12:10PM-

At the dimly-lit center area of the underground, the alliance approach at the door which stopped Petrie, Cera, Ducky, and Littlefoot into going any further as they have their job to protect the door

"This is as far as we go" Littlefoot-2 informed to everyone, giving them the map of the area "Make sure to watch out for Normbots"

"You're not coming?" Ali-2 asked worriedly

"Only Petrie, Cera, Ducky, and I will guard the entrance" Littlefoot-2 "In case if there is an attack, we will engage into battle"

"Thanks, Littlefoot" Ruby-2 thanked him as the rest will proceed to the area, but to note for the alliance is that the room is now awfully dark for Phineas, Ferb, Isabella, Terra, Ruby, and Ali

"Naku, hindi ko maalaala kung ang gitna ng bulkan ay madilim" Terra-2 said suspiciously looking around the area

"Dark?" Ruby-2 asked, giving Both Dimension Phineas and Isabella the willies

"Oops, hindi naman" Terra-2 said while he spotted the light for them to shed onto "Nandito yun ilaw sa gitna…" but when they approach the light, the fast-biter also smell something "At inamoy ko ng langis. Ibig sabihin?"

"That's because it's a trap!"

2D Dr. Doofenshmirtz shine a light around everyone as the Normbots surround them in a circle while 2D Dr. Doof and Furiza walk into them to approach in representation

"Doofenshmirtz, I should've known" Ali-2 said greedily

"...And Furiza Samson" Ruby-2 added while Phineas, Ferb, and Isabella huddle together to prevent their contact with the Normbots

"I have an unexpected surprise for all of you" Furiza said in demeanor as she tugged a chain from her hand which is actually one of the members of Doof Rebellions

"Chomper!" Everyone shouted in surprise as they saw an indigo sharptooth being mildly injured and handcuffed by 2D Dr. Doofenshmirtz

"Hi, everyone" Chomper-2 greeted before ending very enviously, saying in disappointment "So far, this plan isn't going well as I thought of."
