I think it's pretty obvious where Milo and company ended up…

Chapter 4: Return to the Island of Lost Dakotas

"Why does this wall seem familiar? Does this wall seem familiar to you guys?" Dr. Doofenshmirtz wondered aloud as the group assessed the damage from the crash. Thanks to the Phineas and Ferb Effect, no one was injured and the lifeboats were mostly intact. Unfortunately, all the oars were gone, due to the group having to let them go in order to hang onto their boats while riding the giant wave.

Dakota glanced up at the wall. "Uh, oh."

"What's wrong, Dakota?" Milo asked. Phineas and Ferb rushed to stand on either side of the young Murphy, hoping to minimize further damage.

Just then, two men wearing tribal masks that hid their features poked their heads above the wall. "Wego, wego!" they chanted as a third tribal mask appeared.

"Hold on, guys!" the third masked man cried out in English. "Look, it's Cavendish!"

"Cavendish!" cried the first two men as all three of them removed their masks, revealing themselves as Lost Dakotas just as the gate opened. Every Lost Dakota within eyesight stopped what they were doing to rush outside their village to see Cavendish.

"Welcome back to the Island of Lost Dakotas," one of the more tan Dakotas said as he stepped forward. "I'm Chief Dakota. Don't worry, we're not going to haze you guys or anything."

"Oh, yeah?" Dr. Doofenshmirtz said skeptically. "Last time I was here, you Lost Dakotas tied Orton Mahlson and me to a couple of spits like you were going to cook us."

"We only do that to newcomers," Chief Dakota explained. "I mean, we know that you all are cool. And most of us won't eat human flesh."

"Wait, most of you?" Candace interrupted. "So some of you are cannibals?"

"Ew!" Isabella exclaimed.

"I wouldn't knock it until I've tried it," Buford shrugged.

"Nah, just one of us is a cannibal. Oh, that reminds me," Chief Dakota turned toward the crowd of Lost Dakotas gathered behind him. "Can some of you put Cannibal Dakota in his cage, get Really Smelly Dakota to stay upwind and keep Birthday Suit Dakota away from the kids' eyesights."

"Oh, this day keeps getting better and better," Zack said sarcastically.

Melissa nudged Zack in the side. "Come on, you know you love our adventures," she laughed as the group followed the Lost Dakotas into their village.

Zack shrugged, while trying to smother a smile.

Inside the gates, the Lost Dakotas went back to their daily routines as Chief Dakota gave a tour of their village.

"So that was our orange soda factory. Over here is where we manufacture girdles. And over there is where we make laceless shoes."

"Hey, those are the kind that I wear!" Milo exclaimed.

"Oh, yeah, you're our best customer," Chief Dakota said. "Your current pair looks pretty waterlogged. Let's get you a new pair, on the house."

"Gee, thanks!" Milo said.

"Hey, Cobbler Dakotas, get out here!" Chief Dakota yelled through the doorway. "And bring a pair of size 8s with you!"

Three Lost Dakota exited the "Ye Olde Cobbler" building. One was tan and wore an apron. The second Dakota was tan and without an apron. And the third was wearing an apron, but his skin was paler than most of the other Lost Dakotas.

"Here you go, Milo," the pale Dakota said, handing the Murphy boy a pair of shoes.

"How do all the Lost Dakotas know Milo?" Melissa asked Chief Dakota.

"Oh, we know about all of you. We have a movie night where we tap into closed-circuit security cameras all over time and space, so we can keep an eye on Cavendish." Chief Dakota explained. "Some of the more recent footage introduced all of us to the rest of your group- your footage was bound to intersect eventually with all the footage we have of Cavendish and Dakota Prime."

""Dakota Prime." Is that what you Lost Dakotas call me?" Dakota asked as he ambled over with Cavendish.

"Well, we had to call you something," Chief Dakota pointed out. "But even without our movie nights we would have found out about you guys anyway. We saw all of you during the Second Pistachion Takeover in Danville. And some of our more recent arrivals have met most of you in their timelines." Chief Dakota pointed at the pale Lost Dakota who had handed Milo the shoes. "That's the most recent Lost Dakota to arrive. He would have lost his timeline's Cavendish due to some falling debris while on Octalia."

"Wait just one moment! We were banished to this time period long before we traveled to Octalia," Cavendish cried out, turning and poking Dakota in the chest. "When we were raiding the P.I.G. armory, you specifically said you could no longer go back in time and fix things. That we're stuck here now. That we live here now! You said nothing about still having a time machine."

"Yeah about that…" Dakota began, then sighed. "Ok, look. I lied to you."

"Obviously!" Cavendish shouted.

"I really am sorry, Cavendish," Dakota said. "I should have told you that our old lemon of a time machine is still in the parking lot of our rented strip mall office. I should have told you my theory that the Bureau of Time Travel can't track or retrieve our time machine, due to it being such an old model. And I should have told you that I'm still occasionally changing the timeline to save your life."

"Then why didn't you tell me?" Cavendish cried.

"Because if you knew that we still have a time machine, you might take it and leave me!" Dakota yelled.

The entire island held their breath as the two time travelers stared into each other's eyes.

Dakota cleared his throat. "What I mean is, I like it in this time period, but it's more fun with you as a roommate. And you know what I'm going through, being a fellow banished time traveler from the year 2175."

"You really feel that way?" Cavendish asked. "You still want me as a roommate? Even though I went rogue and erased your memory?"

"Well, yeah!" Dakota said. "You're Cavendish…"

"…What are you gonna do!" the Lost Dakotas chimed in.

"Hey, Dakota Prime, you know what goes great with apologies?" Chief Dakota asked.

"Yup!" Dakota said.

"Dinner!" the two Dakotas sang simultaneously.
