"Buford says that the ones responsible for this, as well as every person other than us in our Tri-State Area have been sent to another dimension..." 2nd Candace reminded. "Do you have any idea where, Buford?"
"Nope," 2nd Buford and Ferb answered.
"Huh? How did you know?" 2nd Candace asked.
"Lucky guess." Ferb answered again.
"Well, if that's the case, we have nothing to work with. We have no idea who's behind this or where they have taken everyone..." 2nd Isabella concluded. "What do we do now?"
"We mustn't give up," A voice said behind them. They all turned around.
"Buford? Baljeet?" Isabella classified the two people as the other dimension's friends. "How did you guys get here?"
"Simple, we-" Buford started until Phineas interrupted.
"We're glad you guys could make it," Phineas said. "We could use as much help as we can get."
"Sure," Baljeet agreed.
"Should we go dimension-jumping?" Buford said. "It may take long, but it beats standing here."
"You do have a point," 2nd Candace confirmed. "Just wish we had a hint, at least..." As if on cue, two more figues appear in the EURE. "What are YOU doing here?"
"I'm here on a mission, naturally," 2nd Vanessa answered. "I'm here to prove to you that your brothers aren't who you think they are..."
"This again!?" 2nd Candace exclaimed. "If you so as much as touch my little brothers..."
"I won't need to," 2nd Vanessa said. "I'd like to speak to the Phineas and Ferb from the other dimension..." They approach her. "My boss has informed me you guys have created a device that can scan a person thoroughly. Do you have it with you?"
"Sorry, we left those back home..." Phineas answered.
"I see." she said, disappointed.
"Who's the pharmacist?" Buford asked.
"Oh, this is Dr. Doofenshmirtz from the other dimension. He apparently lost his -inators..."
"They're...in another dimension," Dr. Doof said. "I can sense it..."
"Another dimension, huh?" 2nd Candace said, remembering 2nd Buford saying the same thing. "Tell ya what, Dr. We'll help you find your...-inators but we'll need you to tell us where you sense them...chances are, your -inators and who we're looking for are likely in the same area."
"But sir, this is-" 2nd Jeremy started until he was silenced.
"What other choice do we have?" she replied.
"She's right," Phineas spoke. "Let's get dimension-jumping!"
